Recent results devoted to methods of components compatibilization in polymer blends as well as synthesis and investigation of structure and properties of binary polymer blends was summarized and systematized. Regularities of inter- and intra-molecular physical bonds network formation and the influence on phase structure and properties of heterogeneous systems based on functionalized polymers are thoroughly considered.

With the purpose of parameters optimization of the polymeric materials which are perspective for use in various electrochemical devices, researches of interconnection of internal structure and ionic conductivity of membranes based on cross-linked ammonium interpolymeric complexes (AIPC) are carried out. The complexes were received by interaction of epichlorohydrin gomopolymers or copolymers of epichlorohydrin with ethylene oxide and poly-4-vinylpyridine.
It was established, that AIPC are characterized by a amorphous type of near-field region ordering, and also partial fractal aggregation, features of which can influence on the ions transportation in volume of a polymeric matrix. Ionic conductivity of ammonium interpolymeric complexes activated by orthophosphoric acid and in additional humidified in water is 5.5·10-3 Ohm-1 cm-1 at room temperature.

Film materials based on ammonium interpolymeric complex (AIPC) with high ionic conductivity have been synthesized by co-condensation poly-4-vinylpyridine and polyepichlorohydrine. Their physical-mechanical and electrochemical properties were determined. The AIPC materials were doped by inorganic acids (H3PO4, H2SO4) and proton-conducting materials based on these acids were obtained. It was established, that the film materials are thermally stable up to 250 °C and have conductivity 10-2– 10-4 S·cm-1 at 150 °Ñ.

The dependencies of creep and mechanical relaxation, elongation and stress/strain function, elasticity modulus at elongation and pressure on the chemical composition of organic component of OIS based on oligoetherurethane, polyisocyanate with low molecular weight, and metal silicate were investigated. A good correlation between changes of mechanical parameters and structure of hybrid organic-inorganic network, which is formed during synthesis of OIS have been established.

Methods of TGA and electron spectroscopy were used to analyze the properties of hydroxyl-containing crosslinked poly(glukanurethanes) (PGU) based on xanthan and blocked polyisocyanate as well as of PGU resistance to agressive medium influence. It was found that thermal stability of PGU increases with the urethane group content in PGU. The samples humidity correlates with the amount of hydroxyl groups in PGU. Electron spectra in UV-region demonstrate ability of PGU to phenol sorption from water solutions.

With the purpose of regulation of interphase interaction between components of fiberfilled asphalt bitumen the influence of three types of industrial hydrophising modifiers on interphase interaction between components and on strength of adhesion contacts of three types of bitumens with modified surfaces of fillers was explored.

The nature of viscoelastic anisotropy of polymer high-oriented fibers has been studied. A method of determination of parameters of the heat fluctuations of polymers has been proposed. It has been found that, the striking anisotropy of the heat fluctuations is the characteristsc feature of polymer high-oriented fibers which is expressed by that the crosswise components of susceptibility tenzor of heat fluctuations of deformation exceed on order the longitudinal components.

The general representations about formation, structure and basic physical properties of polymeric brushes are considered. The literary data are complemented by author’s experimental ones. The opportunity of nanoordered polymer brushes creation is shown. The initial backbone conformation is a major factor determining a structure of a polymeric brush: spherical convex brush or brush near a convex cylindrical surface. It was established that the size of polymeric brushes depends on a ratio of backbone to grafts size, as well as their conformation.

New nanocomposites based on linear anionic polyurethane ionomer and montmorillonite were obtained. Nanocomposites were gained by two methods: first method is to synthesize in situ with montmorillonite modified with quaternary ammonium ion, that consists a large aliphatic segment (Ñ12–Ñ14), and the second method is to synthesize in water solutions of ionomer dispersion and montmorillonite sodium form. The montmorillonite content in obtained nanocomposites are in range 1,5 – 2,5 % (weight).These models were investigated by WAX method.
