Polymer composites based on polyvinyl chloride

Binary and ternary polymer blends based on polyvinyl chloride with ethylene–propylene–diene rubber were studied. A comparative analysis of the effect of a low-molecular-weight plasticizer and high-molecular-weight thermoplastic additives on the deformation and strength characteristics of the composites and on the viscosity of their melt was made. The compatibilizing ability of the plasticizing additives and the possibility of the replacement of the low-molecular-weight plasticizer by the polymeric component were evaluated.
