目前,各国学者对硫醇在氯丁二烯乳聚中的行为已有系统的研究,并确认硫醇除了作调节分子量的链转移反应外,还参与其他副反应。例如: 1.硫醇自由基引起的终止反应 Ru·+RS·—→RuSR M_a·+RS·—→M_nSR
At present, scholars in various countries have systematically studied the behavior of mercaptans in the polymerization of chloroprene and confirmed that mercaptans participate in other side reactions in addition to chain transfer reactions that regulate the molecular weight. For example: 1. The thiol radical-induced termination reaction Ru · + RS · - → RuSR M_a · + RS · - → M_nSR
