Abstract
The copolymerization of divinylbenzene and the monomeric quaternary phosphonium salt was studied. The main kinetic regularities and the mechanism of copolymerization are revealed. It is shown that the result of the increase in the thermostability of the copolymer is apparently the participation of the functional-active groups of the allyl monomer in the reactions of intra- and intermolecular cross-linking.

Abstract
Sodium polystyrene sulfonate loaded with dyes brilliant green and acridine orange has been synthesized and described by the methods of IR and UV spectroscopy. Films based on such polymers showed a satisfactory performance in the chemisorption of ammonia, sulfur dioxide, hydrogen sulfide and are a promising optical multisensors for gas analysis.

Abstract
Synthesis of phenolformaldehyde oligomers, modified imidazolines based on natural petroleum acids and polyamines were studied. As the amine compounds in the preparation of imidazolines diethylene triamine, triethylene tetramine, polyethylene polyamines were used. The component, and the mass composition of phenolformaldehyde oligomers, modified with different imidazolines, terms of their receipt were resulted. Significance of the research was grounded.

Abstract
The copolymers of vinyl acetate with 1-vinylimidazole and 4-vinylpyridine were obtained by radical polymerization. Constants reactivity and microstructure parameters of copolymers were calculated and their properties were studied. Composite materials were obtained with sol-gel synthesis involving tetraethoxysilane and copolymers of vinyl acetate with 1-vinylimidazole and 4-vinylpyridine. Also their sorption capacity with ions of platinum (IV) was investigated.

Abstract
Results of the modeling studies of organic compounds adsorption on aluminosilicates modified by synthetic resin, are listed here. We explored the contribution of changes in the structure of "adsorbent - modifier" system on the effectiveness of adsorptive binding. Isotherm that connects adsorption capacity of composite adsorbent and adsorptive equilibrium concentration in solution, was described.

Abstract
The structural-morphological and operational properties of a polymer nanocomposite material based on polyamide-6 have been investigated with the aim of using a hot water supply and heating system as a barrier layer for multilayer pipes. It has been found that this composition is characterized by higher deformation-strength properties and low oxygen permeability at elevated temperatures in comparison with the widely used polyolefins of pipe grades.

Abstract
The principal possibility of combining composite materials on a polymer base by ultrasonic welding is determined. Ultrasound welding of structures consisting of several layers of polymeric composite materials was tested. Technological methods have been developed that ensure preservation or restoration of the initial orientation of the polymer binder that enters the composite.

Abstract
Studied regularities of the influence of moisture absorption on changes in physico-mechanical properties of wood-plastic composites based on recycled polypropylene in the presence of wood flour and rice husk. It is shown that polymer composites based on recycled polypropylene in the presence of rice husk is less absorb moisture compared to using wood flour, which leads to a lower decrease of modulus of elasticity of the material, saturated with water, in the range of filler content of 2-10 weight parts.

Abstract
The article provides brief information on the development of styrene plastics production in the world and Russia. The list of polystyrenes produced and consumed in Russia is discussed. It is shown that at present the assortment of Russian styrene plastics is quite wide and covers practically all fields of application. The exception is special brands, in particular, ESCR grades of high-impact polystyrene, which creates all the prerequisites for creating this production in the territory of Russia in the near future
