AB  - A series of six polyurethane (PU) networks was synthesized from Boltorn® hydroxy-functional hyperbranched polyester (HBP) of the second pseudo generation as a cross-linking agent, a,w-dihydroxy-(ethylene oxide-poly(dimethylsiloxane)-ethylene oxide) (EO-PDMS-EO) and 4,4'-methylenediphenyl diisocyanate, by two-step polymerization in solution. Each sample of the prepared PUs had different EO-PDMS-EO content. The chemical structure of the synthesized networks was analyzed by FTIR spectroscopy. The influence of the EO-PDMS-EO content and type of the solvent on the swelling behavior of the PUs in 2-propanol and toluene was investigated. During the swelling measurements, a certain amount of sol fractions was extracted from the PUs by solvents. According to the 1H-NMR results, sol fractions were mainly composed of the soluble hyperbranched PU, formed during the polymerization by partial modification of the end hydroxyl groups of HBP with NCO-terminated prepolymer synthesized in the first step of the reaction. Chains of the so reacted prepolymer can then fold back and form cyclic products by reaction of the free -NCO group from the NCO-terminated prepolymer with free -OH group of HBP. As the EO-PDMS-EO content increases the amount of the sol fractions and swelling degree also in- creased, indicating that networks with lower EO-PDMS-EO content are more cross-linked and have higher solvent resistance.
AB  - Serija od šest uzoraka poliuretana je sintetisana polazeći od komercijalnog alifatskog Boltorn® hidroksi funkcionalnog hiperrazgranatog poliestra druge pseudo-generacije kao umreživača, a,w-dihidroksi-(etilenoksid-poli(dimetilsiloksan)-etilenoksid) (EO-PDMS-EO) i 4,4'-metilendifenildiisocijanata primenom dvostepene polimerizacije u rastvoru. Svaki sintetisani uzorak umreženog poliuretana je imao različiti sadržaj EO-PDMS-EO. Hemijska struktura pripremljenih uzoraka poliuretana je analizirana FTIR spektroskopijom. Ispitan je uticaj sadržaja EO-PDMS-EO i vrste rastvarača (2-propanol i toluen) na svojstva sintetisanih umreženih poliuretana pri bubrenju. Prilikom bubrenja došlo je do izdvajanja sol frakcija iz sintetisanih uzoraka koje su nakon uparavanja rastvarača ispitane 1H NMR spektroskopijom. Dobijeni rezultati ukazuju na to da se sol frakcija uglavnom sastoji od rastvornog hiperrazgranatog poliuretana nastalog u toku reakcije polimerizacije kao posledica parcijalne modifikacije krajnjih hidroksilnih grupa hiperrazgranatog poliestra NCO-terminiranim pretpolimerom sintetisanim u prvom stupnju reakcije. Lanci tako proreagovalog pretpolimera su se najverovatnije zatim savili, pri čemu je došlo do dalje reakcije između preostale -NCO grupe sa nekom slobodnom -OH grupom iz hiperrazgranatog poliestra i formiranja ciklika, čime je određeni broj -NCO i -OH grupa blokiran za dalju reakciju umrežavanja. Pokazano je da stepen bubrenja i procenat sol frakcije sintetisanih uzoraka u oba rastvarača raste sa povećanjem sadržaja EO-PDMS-EO, što ukazuje da su uzorci sa nižim sadržajem EO-PDMS-EO više umreženi.

AB  - World packaging market achieves turnover of about $620 billion per year with one third of this amount being associated with packaging made from polymer materials. It is expected that this kind of packaging consumption will hold at least 3% of the world packaging market share in the next five years and that it will surpass the consumption of all other materials used in the packaging production. This can be contributed to product quality, low production costs as well as significant investments made in the development of polymer materials, packaging technology and packaging. This paper presents some development directions for packaging made from polymer materials, such as: packaging in protective atmosphere, the use of active and intelligent packaging, and the use of biopolymers and recycled polymers for packaging production that come into direct contact with the packed product.
AB  - Na svetskom tržištu ambalaže godišnje se ostvari promet od oko 620 milijardi US dolara. Jedna trećina ove sume otpada na ambalažu od polimernih materijala. Očekuje se da će porast potrošnje ambalaže od polimernih materijala biti najmanje 3% u sledećih pet godina i da će biti veći od porasta potrošnje svih drugih materijala, koji se koriste za izradu ambalaže. Zbog kvaliteta i cene polimerni materijali polako istiskuju druge materijale i u ovoj oblasti primene. Veliki doprinos tome daju proizvođači polimernih materijala i ambalaže od polimernih materijala, kao i svi oni koji koriste ovu ambalažu za pakovanje svojih proizvoda, značajnim ulaganjem u razvoj polimernih materijala, tehnologiju izrade ambalaže i pakovanja. U okviru ovoga rada prikazani su neki od pravaca razvoja ambalaže od polimernih materijala, kao na primer: pakovanje u zaštitnoj atmosferi, primena aktivne i inteligentne ambalaže, sve veća primena biopolimera i reciklata polimera za izradu ambalaže koja dolazi u direktan kontakt sa pakovanim proizvodom.

AB  - In this paper, properties of the commercially available Boltorn® hydroxy-functional aliphatic hyperbranched polyesters of the second, third and fourth pseudo generation, were investigated. Additionally, samples of the third and fourth pseudo generation were fractionated using the precipitation fractionation method to obtain three fractions of each sample, which were also investigated in this paper. According to the results obtained by GPC analysis, molar mass and polydispersity of the investigated Boltorn® hyperbranched polyesters increased with increase of the pseudo generation number. Value of the limiting viscosity number of the investigated samples, determined using the viscosity measurements of dilute solutions of these polymers in N-methyl-2-pyrrolidone, increased with the increase of the pseudo generation number. On the other hand, the value of the limiting viscosity number of the fractions decreased from the first up to the third fraction. The same trend was also observed for the values of the hydrodynamic diameter of parent samples and their fractions, determined by dynamic light scattering using N-methyl-2-pyrrolidone as solvent. The thermal properties of the investigated Boltorn® hyperbranched polyesters were determined by thermogravimetry in nitrogen atmosphere and it has been shown that thermal stability of these samples increased with increase of the pseudo generation number. End hydroxyl groups of the second and third pseudo generation samples were modified with β-alanine to obtain hyperbranched samples soluble in water. That was fully accomplished only for the Boltorn® hyperbranched polyester of the second pseudo generation. On the other hand, it was possible to dissolve the modified sample of the third pseudo generation in water only after adding a small amount of the NaOH.

Primenom GPC analize pokazano je da sa povećanjem broja pseudo generacije dolazi do rasta molarne mase ali i polidisperznosti ovih uzoraka. Vrednosti graničnog viskozitetnog broja i hidrodinamičkog prečnika ispitivanih poliestara, određenih u N-metil-2-pirolidonu kao rastvaraču, rastu sa povećanjem broja pseudo generacije, dok kod frakcija ove vrednosti opadaju od prve do treće frakcije. Na osnovu termogravimetrijskih rezultata konstantovano je da termička stabilnost ovih uzoraka raste sa povećanjem broja pseudo- generacije. Modifikovanjem krajnjih hidroksilnih grupa Boltorn® hiperrazgranatog poliestra druge pseudo generacije β-alaninom dobijen je uzorak rastvoran u vodi, dok se uzorak treće pseudo generacije, takođe modifikovan β-alaninom, rastvorio u vodi nakon dodavanja male količine NaOH.

AB  - Macroporous crosslinked poly(GMA-co-EGDMA) was synthesized by the suspension copolymerisation and functionalized by the ring-opening reaction of the pendant epoxy groups with ethylene diamine. The porosity parameters (specific pore volume, specific surface area, and pore diameter, which corresponds to half of the pore volume) for the initial and amino-functionalized copolymer samples were calculated from the cumulative pore volume distribution curves obtained by mercury porosimetry. The selectivity, sorption capacity and sorption rate of amino-functionalized poly(GMA-co-EGDMA)-en were determined under static conditions. The sorption of Cu(ll) and Ag(l) ions on poly(GMA-co-EGDMA)-en was very rapid (ti/2 value about 1 min). Slower sorption was observed for Au(lll) ions with a ti/2 value of 6.5 minutes. The different rates of Au(lll), Cu(ll) and Ag(l) sorption could be applied for gold, copper and silver ion separation from mixed solutions. The sorption of Ni(ll) and Cu(ll) ions from galvanic solution under competitive conditions was also fast, with ti/2 values of 0.5 and 2 min, respectively. However, Zn(ll) sorption was considerably slower (a ti/2 of 10 min). Similar results were obtained for galvanic solution under dynamic conditions, i.e., the metal sorption capacities of poly(GMA-co-EGDMA)-en decreased in the order: Ni(ll) > Cu(ll) >> Zn(ll). The reusability of amino-functionalized poly(GMA-co-EGDMA) for Cu(ll) sorption was tested in four sorption/desorption cycles. Regeneration experiments were performed with 0.1 and 1 M H2SO4 showed a Cu(ll) capacity loss of 50 % in the first sorption/desorption cycle. The sorption capacity increased when additional neutralization with 0.1 and 1 M NaOH was performed after each sorption/desorption cycle.

AB  - Two samples of macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate),
poly(GMA-co-EGDMA), with different porosity parameters were synthesized by suspension copolymerization and
modified by ring-opening reaction of the pendant epoxy groups with ethylene diamine (EDA). The samples were
characterized by mercury porosimetry, FT-IR spectroscopy and elemental analysis. The sorption rate of the modified
copolymer, poly(GMA-co-EGDMA)-en for Cu(II) ions determined under non-competitive conditions was relatively
rapid, i.e. the maximum capacity was reached within 30 min. Batch sorption capacities for Cu(II), Fe(II), Mn(II),
Cd(II), Zn(II), Pb(II), Cr(III) and Pt(IV) ions were determined under non-competitive conditions in the pH range 1.25–
5.5 at room temperature. The maximum sorption capacities of poly(GMA-co-EGDMA)-en under non-competitive
conditions were 1.30 mmol/g for Pt(IV) at pH 5.5, 1.10 mmol/g for Cu(II) at pH 5.5, 1.06 mmol/g for Pb(II) at pH 1.25
and 0.67 mmol/g for Cd(II) ions at pH 5.5. The selectivity of poly(GMA-co-EGDMA)-en towards Cu(II), Co(II),
Ni(II), Pb(II) and Pt(IV) ions was investigated under competitive conditions. Poly(GMA-co-EGDMA)-en showed high
selectivity for Pt(IV) over Cu(II), Co(II), Ni(II) and Pb(II) ions at pH 2.1. At pH 5.5, the metal sorption capacities of
poly(GMA-co-EGDMA)-en decreased in the order: Cu(II)>Co(II)>Pt(IV)_Ni(II)>Pb(II). Regeneration of the
Cu(II), Ni(II) and Pb(II) loaded poly(GMA-co-EGDMA)-en with 2 M H2SO4 showed that the polymer can be reused
in several sorption/desorption cycles.

AB  - The results obtained during the investigation of the influence of the inert component composition and the type of copolymerization reaction on the porosity parameters of the macroporous copolymer of glycidyl methacrylate (GMA) and ethylene glycol dimethacrylate (EGMA) [abbreviated poly(GMA-co-EG-DMA)] are presented. A mixture of cyclohexanol and aliphatic alcohol or non-ionic surfactants with hydrophilic-lipophilic balance values (HLB) of 5 or 9 was used as the inert component. The copolymerization was performed in suspension and in a cast. It was shown that poly(GMA-co-EGDMA) samples with enhanced porosity were obtained in the case of copolymerization in a cast, compared with samples obtained by suspension copolymerization. Also, it was concluded that the inert component solubility parameter cannot be used as the only criterium which determines the formation of the macro porous structure in poly(GMA-co-EGDMA).
AB  - U okviru ovoga rada prikazani su rezultati dobijeni izučavanjem uticaja sastava inertne komponente i načina izvođenja reakcije kopolimerizacije glicidilmetakrilata (GMA) i etilenglikol dimetakrilata (EGDMA) na parametre porozne strukture sintetizovanog makroporoznog poli(GMA-co-EGDMA). U svojstvu inertne komponente korišćena je smeša cikloheksanola i jednog alifatskog alkohola ili nejonske površinski aktivne supstance sa HLB vrednošću 5 ili 9. Reakcija kopolimerizacije je izvođena u suspenziji i u kalupu. Pokazano je da se izvođenjem kopolimerizacije GMA i EGDMA pri istom sastavu reakcione smeše u kalupu dobija poli(GMA-co-EGDMA) sa većom poroznošću nego pri suspenzionoj kopolimerizaciji. Pokazano je takođe da parametar rastvorljivosti inertne komponente ne može da se koristi kao jedini kriterijum koji određuje nastajanje porozne strukture makroporoznog poli(GMA-co-EGDMA).

AB  - Macro porous cross linked poly(GMA-co-EGDMA) copolymer synthesized by radical suspension copolywerization was modified by ring-opening reaction of the pendant epoxy groups with ethylene diamine, EDA. Sorption capacities and selectivity for Cu2*, Ccr+ and' Nf¥ ions were determined under non-competitive conditions as a function of pH and porosity parameters of synthesized samples. Selectivity of modified copolymer for Cif+, Ccr+ i Nf+ ions as a function of pH, as well as the possibility of selective removal of platinum from mixed solutions with copper ions were determined under competitive conditions.
AB  - Makroporoznipoli(GMA-co-EGDMA) kopolimer sintetizovan je suspenzionom kopolimerizacijom, a zatim modifikovan sa etilendiaminom. Ispitana je sorpciona sposobnost i selektivnost modifikovanog kopolimera za jone bakra, kobalta, nikla i platine. Brzina sorpcije i kapacitet modifikovanog kopolimera za Cif", Ccr+ i Nf* jone određeni su pri nekompetitivnim uslovima u zavisnosti od parametara porozne strukture ispitivanih uzoraka i pH rastvora iz koga se vrši sorpcija. Pri kompetitivnim uslovima ispitana je selektivnost modifikovanog kopolimera prema jonima Cif', Cer* i Nf+ u zavisnosti od pH, kao i mogućnost selektivnog izdvajanja jona platine iz mešanog rastvora sa jonima bakra.
