The objective of the reaserch is to elaboration the composition of a wood-polymer composition based on polyvinyl chloride with improved performance properties. The influence of the components of the composition - modifiers, lubricants, regulators and stabilizers - on the properties of the composition was researched. Optimization of the composition of wood-polymer composition based on PVC made it possible to obtain a material with higher strength and fire resistance.

The authors investigated the possibility of increasing the basic operational properties of polyurethane foam by introducing such mineral fillers as clay, loam, sand, and others, including man-made ones. For the first time polyurethane foam filling with industrial waste from mining and processing plants, in particular, wet magnetic separation of ferruginous quartzites (hereinafter - tailings) was proposed. The resulting insulating composites with improved performance properties will expand the use range of the material in construction.

Abstract The questions of interaction of one-component polyurethane and organosilicon compound from the group of alkoxysilanes - tetrapropoxysilane are considered. The composition is intended to obtain a hydrophobic coating with improved performance properties to protect building structures from the effects of technogenic and natural factors. The mechanisms of interaction of one-component polyurethane with tetrapropoxysilane have been studied using spectroscopy. The product of the interaction of the polymer and tetrapropoxysilane is a three-dimensionally crosslinked polymer in which polyurethane macromolecules are crosslinked by organosilicon molecules. The chemical reaction is based on the mechanism of interaction of isocyanate groups with reactive groups of alkoxysilane. The effect of the modifier on the surface structure of the cured coating was studied using a microscope. The contact angle of wetting of the modified and unmodified composition is determined, and the concentration of tetrapropoxysilane at which the coating acquires hydrophobic properties is determined. The effect of tetrapropoxysilane on the adhesive characteristics of the polymer composition has been studied. The change in the hardness of the composition at various concentrations of alkoxysilane was studied. Chemical modification of polyurethane allows you to vary its properties in the desired direction without deteriorating its other characteristics.

The main methods of physical modification of PVC materials is the combination with other polymers, including PS plastic, and the creation of polymer (nano) composites containing metal and silicate fillers. Modification of polyvinyl chloride by polystyrene plastic leads to obtain materials with reduced degree of plasticizer release out of matter volume, adjustable elastic-plastic characteristics, and enhanced physico - mechanical and thermal properties. Physical modification of vinyl chloride polymers by other polymers or nanoscale particles of inorganic nature enables predictable affect on the morphology of these materials and directed regulate their technological and performance properties.
