引发剂在氯乙烯共聚中的应用

Application of initiators in vinyl chloride copolymerization

介绍了在氯乙烯共聚中引发剂的选择方法,研究了温度与引发剂用量对聚合时间的影响。结果表明:在52、57、62℃使用引发剂D的用量分别为1．87、1．62、1．34 mmol时氯乙烯共聚的时间最短。

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 resuits 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.
