Novel crosslinked polyurethanes based on hyperbranched polyesters
(Society of Physical Chemists of Serbia, 2010)
The polyurethane (PU) elastomers based on hydroxy-terminated hyperbranched polyester (BH-20) and 4,4-methylenediphenyl diisocyanate (MDI) as hard segments and hydroxyl-terminated ethylene oxide-poly(dimethylsiloxane)-ethylene ...
Critical manifold of the model for Bray-Liebhafsky oscillatory reaction
(Society of Physical Chemists of Serbia, 2010)
Mixed mode oscillations are obtained in numerical simulations of the Bray-
Liebhafsky oscillatory reaction in CSTR, for appropriate choice of the parameter
set. In this paper, we analyze critical manifold of the slow-fast ...
Methanol electrooxidation from alkaline solution on pt and PtRu modified Zeolite X
(Society of Physical Chemists of Serbia, 2010)
Zeolite NaX was modified by Pt and Pt/Ru nanodispersed metallic clusters. This
modification was achieved by zeolite impregnation with acetylacetonate salt/acetone
solution, followed by acetone evaporation and thermal ...
Size distributed aerosol mass concentration and chemical composition in Belgrade during summer-autumn 2008
(Society of Physical Chemists of Serbia, 2010)
Physical and chemical characterizations of the atmospheric aerosol were carried out in urban area of Belgrade. This work focuses on the size-segregated aerosol chemical composition observed during the summer-autumn 2008th. ...
Influence of bentonite filler on the thermal stability of glycidyl methacrylate based composite
(Society of Physical Chemists of Serbia, 2010)
Macroporous crosslinked copolymer of glycidyl methacrylate, GMA, and ethylene
glycol dimethacrylate, EGDMA, poly(glycidyl methacrylate-co-ethylene glycol
dimethacrylate) and its composites were synthesized by ...
The Kinetics of Reaction between Iodide and Hydrogen Peroxide in Acid Solution
(Society of Physical Chemists of Serbia, 2010)
The kinetics of the complex reaction between I– and H2O2 in acid media is investigated. The particular attention is focused on the determination of the rate
constant of the reaction between HIO and H2O2 involved in ...
Rheological and thermal properties of Boltorn® hyperbranched polyesters
(Society of Physical Chemists of Serbia, 2010)
Rheological (in solution and in melt) and thermal properties of aliphatic hydroxy-functional Boltorn® hyperbranched polyesters of different pseudo generation were investigated in this work. The obtained results show that ...
