The properties of blends filled with polymers of a different structure and low molecular weight additives were analyzed. Additives selection is grounded. It was established that three-component polymer blends have a sufficient fluidity value, which ensures the ability of obtained materials to be processed. The influence of the composition and nature of the components on the physical and mechanical properties of obtained compositions was studied. The adding of mineral filler into the polymers blend helps to increase dispersion and thus expands of application of mentioned polymer owning to their possibility to be processed.
