在前篇文章中已证明,在自由基聚合过程中,通过使用某些取代酚的二硫化物作为链传递剂,能够赋与聚二烯的均聚或共聚物有效的自抗氧化性能。众所周知,某些烷基或芳烷基硫醇,以及胺取代的芳基二硫化物,例如双(2-胺基苯基)二硫化物,能与聚合物基团进行链传递反应。也知道芳基和芳烷基硫醇能够紧密地联系自由基反应,加到聚二烯烃存在 It has been shown in previous articles that by using certain substituted phenol disulfides as chain transfer agents during homopolymerization of free radicals effective homopolymer or copolymer self-oxidation resistance of polydiene can be imparted. It is well known that certain alkyl or aralkylthiols, as well as amine-substituted aryl disulfides, such as bis (2-aminophenyl) disulfide, can undergo chain transfer reactions with polymer groups. It is also known that aryl and aralkylthiols are capable of intimately associating with free radical reactions to the presence of polydienes
