Application of initiators in vinyl chloride copolymerization

The methods of initiator selection for vinyl chloride copolymerization are introduced, the influence of temperature and use level of initiator on time of copolymerization has been studied. The results show that, the copolymerization time of vinyl chloride is the least when the use level of initiator D is 1.87,1.62 and 1.34 mmol,resp. at the temprature of 52,57 and,62℃ resp.
