Abstract

The main aim of this review study is to summarise the progress and recent modifications in the area of functionalised PVC including chlorinated PVC, PVC copolymers and their composite developments. Functionalized PVC and its copolymers shown very good improved properties which enhanced the PVC application domain as compare to other polymers. Due to the higher chlorine content polyvinyl chloride (PVC) shows higher mechanical and fire-resistive properties which are suitable for building construction materials. PVC is also very good for piping, electrical and several other applications including the medical and toy sector. Chlorinated polyvinyl chloride (CPVC) synthesis by different methods and the dependence of chlorine content on different reaction parameters are well established and studied in detail. Functional PVC and PVC copolymer and their related composites are very essential functional materials as they depict excellent performance in terms of mechanical properties, ease of processing, dispersion phenomenon and high thermal properties. Due to these behaviours modified PVC materials have opened a new and improved applications and opportunities in various areas like medical, sports, packaging and building constructions. Composite products based on functionalized PVC is also taken the interest of industries and researchers. Functionalized PVC composite products show better performance and structural stability. These functionalized PVC composites give better compatibility or miscibility with other polymers which also open new opportunities to make different products for various new applications. These functionalized polymers can also be utilized to avoid or reduce the mixing of different plasticizers during the processing of PVC based composite or blending formulations.
