Graft Copolymers with a Backbone of Polyvinyl Chloride): Synthesis, Properties, and Applications

Abstract

Poly(vinyl chloride) (PVC) has occupied the most important position among the general purpose plastics, but its industrial applications are limited due to its inferior thermal stability and mechanical properties. It has been observed that the removal of tertiary or allylic chlorine atoms or some other abnormal and unstable structures from polymeric chains, by graft copolymerization with vinyl monomers, improves the thermal stability and mechanical properties (such as softening temperature, rigidity, anticreep properties, impact strength, and tensile strength) of PVC to a large extent.
