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
