摘要
苯乙烯和二乙烯苯共聚体系是典型的不可控制的交联聚合体系,加入天然橡胶后,通过阳离子聚合方法,生成三元共聚物线团,由于橡胶分子链上含有大量的双键,聚合体系中能进行分子内反应,使不可控的交联聚合体系成为可控的交联聚合体系,其链增长不能无限制进行,从而可以合成可溶解的交联的聚苯乙烯-二乙烯苯-天然橡胶聚合物。
Copolymerization of styrene and divinylbenzene is typical uncontrolled cross-linked system. When natural rubber was added into the system, ternary copolymer produced. Due to great amount of double bond on rubber chain, a lot of intramolecular reaction occurred in the system, which made the uncontrolled cross-linked system into a controlled cross-linked copolymerization, resulting in chain growth can't go illimitably in cross-linking process. Thus, soluble cross-linked poly (styrene-divinylbenzene-natural rubber) was synthesized.
