Characterization of the commercial hyperbranched polyesters / Karakterizacija komercijalnih hiperrazgranatih poliestara
(Association of Chemical Engineers of Serbia, 2010)
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 ...
The application of macroporous copolymers in the sorption of heavy and precious metals from aqueous solutions / Primena makroporoznih kopolimera u sorpciji teških i plemenitih metala iz vodenih rastvora
(Association of Chemical Engineers of Serbia, 2006)
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 ...

Commercial macroporous poly(4-vinylpyridine-co-divinylbenzene) [P4VPD], known as Reillex-425, was characterized by mercury porosimetry, nitrogen physisorption, Fourier transformed infrared (FTIR) spectroscopy and elemental ...
Direct liquefaction of soft brown coal from the Kosovo basin / Likvefakcija mekog mrkog uglja kosovskog basena
(Association of Chemical Engineers of Serbia, 2000)
The behavior of Kosovo Basin (Yugoslavia) soft brown coal was studied during a direct liquefaction process by catalytic hydrogenation. A stream of hydrogen was passed through a tetralin dispersion of the pulverized coal ...
Investigation of pretertiary and tertiary surface sediments from Serbia: Organic geochemical interpretation / Ispitivanje pretercijarnih i tercijarnih površinskih sedimenata Srbije - organsko-geohemijska interpretacija
(Association of Chemical Engineers of Serbia, 2002)
Samples of surface sediments originating from different localities in Serbia which contained more than 0.5 % organic matter were investigated in this paper. According to age, these samples were classified into two groups ...
