Study of Polymer Matrices Based on Blends of Polyvinyl Chloride and Grafted Copolymers

The development of mixed matrices is a well-established and suitable method for obtaining new polymeric materials. The combination of two different types of polymers allows you to get a new and unique material that has the properties of both polymers. This paper compares polymer matrices based on polyvinyl chloride (PVC) and various graft copolymers in order to select the optimal compositions for further filling. Domestic acrylonitrile butadiene styrene (ABS) and imported acrylonitrile styrene acrylate (ASA) were chosen as graft copolymers. Despite the manufacturability of copolymers, the subsequent extrusion of filled compositions is more appropriate with a PVC/ABS matrix, since power consumption during processing will be reduced. At the same time, the matrix based on a mixture of PVC/ASA polymers has higher strength properties, but PVC/ABS has the best effect as an impact-resistant matrix. Depending on the content of the copolymer, the structure of compositions based on polymer mixtures can be microdispersed or viscous and layered, which will determine the main physical and mechanical properties. In general, both matrices can be used for further filling, but with a copolymer content of less than 50 phr.
