The effect of the kind, concentration and introduction method of polymeric modifiers (polyvinyl alcohol and polyvinylpyrrolidone), as well as the kind of metal chloride on the physico-chemical regularities of the obtaining process of modified metal-containing polymersilicate materials, their morphology and properties has been examined. Using instrumental methods of investigations it was established that obtaining of metalcontaining polymer-silicate materials was accompanied by intermolecular interactions between active silicate groups and functional groups of a polymeric modifier. The effect of metal-containing polymer-silicate materials on the regularities of curing and properties of polyester composites has been studied.

The influence of talc filler, its content, as well as an additional heat treatment and temperature on the regularities of polylactide materials water-absorption has been researched. Based on the obtained data, the water diffusion coefficient in polylactide materials and the activation energy of the diffusion process were determined. It was found that the process of water absorption by the filled and heat-treated materials based on polylactide proceeds slower and requires more activation energy of the process. Stability of the developed polylactide materials to acidic and alkaline media has been determined, in particular, it was found that the destruction of polylactide samples occurs faster in an alkaline medium than in an acidic one

Sorption properties of materials based on sodium liquid glass modified by polyvinyl alcohol and polyvinylpyrrolidone on regarding to different acid-base indicators were investigated. The effect of the nature of metal and polymer modifier (polyvinyl alcohol and polyvinylpyrrolidone) on the amount of active centers and specific active surface area of such material was determined. Moisture absorption of modified and not modified silicate materials was founded. The effect of Ni-containing polymer-silicate materials on the speed of curing of compositions based on unsaturated polyester resins was determined.
