| 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。

| Abstract: | 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. |

| Keywords: | intramolecular reaction intermolecular reaction controlled cross-linking polymerization soluble cross-linked macromolecule |
