This study aims to demonstrate the feasibility of obtaining wood-polymer composites, which focus on materials that are difficult to recycle. For this purpose, local poplar and pavloniya wood samples, the density of which corresponds to this process, were impregnated with polyvinyl chloride and CaCO3, which form free radicals. Samples were taken using a hot press. Physico-mechanical parameters of the samples were analyzed. Due to the low permeability of the poplar wood showed only increasing values of stiffness parallel and perpendicular to the grain. Undebarked ponderosa pine chips were treated by hot water extraction to modify the chemical composition. In the treated pine (TP), the mass was reduced by approximately 20%, and the extract was composed mainly of degradation products of hemicelluloses. Wood flour produced from TP and unextracted chips (untreated pine, UP) was blended with high-density polyethylene (HDPE) and polypropylene (PP) and was extruded into wood plastic composites (WPCs).
