Research Progress on Modification of 1,2-Polybutadiene Rubber

概述以自由基加成反应、催化加成反应和烯烃复分解反应3种方式对1,2-聚丁二烯橡胶(简称1,2-聚丁二烯)改性的研究进展,并分析各种改性方式的特点。向分子中引入极性官能团可改善1,2-聚丁二烯与极性配合剂的相容性,提高加工性能、物理性能和热稳定性能,获得特殊功能性(如循环性、表面粘性、可降解性、自愈性和形状记忆等)。分子侧链丰富的乙烯基为1,2-聚丁二烯改性提供了多种可能性。

The research progress on the modification of 1,2-polybutadiene rubber(referred to as 1,2-polybutadiene)by free radical addition reaction,catalytic addition reaction and olefin metathesis reaction was summarized,and the characteristics of the modification methods were analyzed.The introduction of polar functional groups into the molecule could improve the compatibility of 1,2-polybutadiene with polar complexing agents,improve processing performance,physical properties and thermal stability,and obtain special functions(such as cycleability,surface tackiness,degradability,self-healing,shape memory,etc).The rich vinyls on molecule side chains provided many possibilities for 1,2-polybutadiene modification.
