Synthesis and characterization of aliphatic hyperbranched polyesters
(The Society of Chemists and Technologists of Macedionia, 2008)
The synthesis of dendritic polymers, i.e., dendrimers (ideally branched) and hyperbranched polymers (non-ideally
branched) and investigation of their properties have gained large scientific attention over the last twenty ...
Synthesis and characterization of crosslinked polyurethanes
(The Society of Physical Chemists of Serbia, 2008)
Two polyurethane samples, crosslinked with aliphatic hyperbranched polyester, were synthesized and examined in this work. The sample PUPDMS-EO was prepared using ethylene oxide-poly(dimethylsiloxane)-ethylene oxide as ...
Influence of α-Fe2O3 nanorods on the thermal stability of poly(methyl methacrylate) synthesized by in situ bulk polymerisation of methyl methacrylate
(Elsevier, 2008)
α-Fe2O3 nanorods were incorporated into poly(methyl methacrylate) (PMMA) by in situ radical polymerisation of methyl methacrylate initiated by 2,2′-azobisisobutyronitrile. The α-Fe2O3 nanorods were synthesized by forced ...
Hyperbranched Polymers Based on Aliphatic Polyesters – Synthesis and Characterization
(Saarbrücken, Deutschland : VDM Verlag Dr. Müller Aktiengesellschaft & Co. KG, 2008)
Two series of hydroxy-functional hyperbranched polymers based on aliphatic polyesters have
been prepared from the 2,2-bis(hydroxymethyl)propionic acid (AB2 monomer) and the ditrimethylolpropane
(B4 functional core). A ...
Sinteza alifatskih hiperrazgranatih poliestara: "pseudo one-step" procedura“
(Belgrade : Serbian Chemical Society, 2008)
Hiperrazgranati polimeri (HBP) i dendrimeri pripadaju klasi dendritskih makromolekula. Za razliku od složene i dugotrajne sinteze dendrimera, HBP se mogu sintetisati korišćenjem jednostavne "one-step" procedure, pri čemu ...
Rheological and thermogravimetric analysis of unmodified and modified aliphatic hyperbranched polyester
(The Society of Physical Chemists of Serbia, 2008)
The influence of the type of end groups on the rheological and thermal properties of aliphatic hyperbranched polyesters (AHBP) was investigated in this work. Unmodified, hydroxy-functional AHBP sample of third pseudo ...
Thermal behaviour of Ag/PMMA nanocomposites synthesized by in situ method
(Institute of Technical Sciences of the Serbian Academy of Sciences and Arts, 2008)
The influence of the surface modified silver nanoparticles (Np), used as a filler, on the thermal properties poly(methylmethacrylate) (PMMA) matrix, synthesized by “in situ” radical polymerization process, was studied. The ...
Termičke karakteristike nanokompozita Ag/PS
(Društvo inženjera plastičara i gumara IPG, Beograd, Srbija, 2008)
U radu je ispitivan uticaj nanočestica srebra (Ag) na termičke karakteristike polimerne matrice polistirena (PS). Ispitivanja su vršena metodom termogravimetrijske analize (TGA) u azotu u zavisnosti od koncentracije ...
Sinteza i karakterizacija nanokompozita Ag/PS
(Belgrade : Serbian Chemical Society, 2008)
Ispitivan je uticaj površinski modifikovanih nanočestica srebra (Ag) na optičke i termičke osobine matrice polistirena (PS). Obojeni transparentni nanokompozitni filmovi, dobijeni direktnim mešanjem nanočestica Ag i ...
Thermal studies of silver- poly(methylmethacrylate) nanocomposites
(The Society of Physical Chemists of Serbia, 2008)
The novel nanocomposite material based on surface-modified silver nanoparticles (Np) with average diameter of 6 nm and poly(methylmethacrylate) (PMMA) matrix was synthesized. The effect of silver loading on the thermal ...
