This paper provides a summarized review on the kinetics of vinyl chloride homopolymerization in the absence and presence of chain transfer agents, of VC/DAP(diallyl phthalate) copolymerization with chain extension and/or slightly crosslinking functions, and of vinylidene chloride/VC random copolymerization. Models of rate, degree of polymerization or molecular weight, copolymer composition, gel fraction and crosslinking density were proposed and interpreted mechanistically. 展开更多

The development of conducting polymers has been an active subject in the world since the late in 1970’s. The preparation of polyaeetylene-like polymers by dehydroehlorination of polyvinylchloride (PVC) is a very economical and useful procedure and,hence, a focus of enormous interest of both theoretieians and experimentalists. In recent years, many methods for dehydrochlorination of PVC in solution have been studied widely and many kinds of catalytic mechanisms have been suggested. 展开更多
