SYNTHESIS AND PROCESSING OF POLYMERS AND POLYMERIC COMPOSITES

3-25 38
Abstract
The work looks at a number of crucial stages in the development of Russia rubber industry that is celebrating its 175-th anniversary this years
26-31 54
Abstract
Aspects of creation of elastomeric membranes widely applied as sensitive elements and regulators power elements are considered
32-37 42
Abstract
Variety of graphic representations invoked by error presence in solving of singlefactor and multiple-factor tasks, important in elastomer system properties optimization, is considered here
38-41 34
Abstract
The opportunity of modification of adhesives based on nitrile-butadiene rubber with chlorinated PVC is shown
42-46 42
Abstract
Ecological and economic problems of rubber goods recycling are considered. In this paper we shall present results of research of influence rubber crumbs on technological and physico-mechanical properties of elasromeric materials
47-51 36
Abstract
The influence of polymer molecular weight on adhesion properties and role of adhesion promoter are shown
52-55 43
Abstract
Positive influence on a complex of technological, physico-mechanical and electric elastomeric material properties at use of a combination of carbon black and the certain order of their introduction was established
56-59 230
Abstract
Influence of IPPD on brass-plated steel cord bonding to rubber, in presence of cobalt salts as adhesion promotors, was investigated. It was found that adhesion of 3L30 steel cord to breaker rubber, containing Co stearate and naphtenate as adhesion promotors, increased in presence of IPPD

Abstract
The effect of crosslink density (Nc) of the inner EPDM rubber phase on the coalescence of its domains during capillary extrusion of 20/80 EPDM/PP blends has been studied. The EPDM phase was preliminary loaded with varying amounts of vulcanization agents followed by the reactive blending with PP matrix on a roll mill at 185 o C. The samples were extruded through a capillary rheometer at 185 o C. It is demonstrated that even at low shear rate the convergent flow results in strong coalescence efficacy of droplets in raw blends and in complete suppression of coalescence at low Nc.

Abstract
Reaction of splitting of carboranes (12) under action of ammonia were investigated by the B3PW91/6-31G(d,p) method. Separate stages of process are found and quantitatively characterized. Thermodynamic and kinetic parameters of reactions were calculated
72-77 68
Abstract
The effect of support nature on activity of low-temperature carbon monoxide oxidation catalysts was studied. It is shown on the base of X-ray Diffraction, that y-Al2O3 is the best support for Pd-Cu catalyst

CHEMISTRY AND TECHNOLOGY OF MEDICINAL COMPOUNDS AND BIOLOGICALLY ACTIVE SUBSTANCES

78-82 47
Abstract
The photoaffine arylazide semax derivative has been synthesized using paminobenzoic acid and semax as starting compounds
83-89 61
Abstract
Synthesis of amphiphilic meso-arylsubstituted porphyrins with hydrophobic long chain groups and with terminal carboxylic and hydroxylic groups via dipyrrolylmethanes and with the use of monopyrrolic condensation is described. The synthesized porphyrins will allow studying the influence of fragments of amphiphilic structures of porphyrins on self-aggregation of porphyrins in micellar and bilayer model membrane systems
90-91 37
Abstract
An alternative approach for description of phase equilibria in quaternary systems MI2 – Ur – I2 – H2O at 00 С as compared with the published one («Vestnik MITHT», 2006, №1, pp.66-70) is given
