补充资料：IR
聚异戊二烯橡胶是由异戊二烯单体经溶液聚合而得，简称IR。由于异戊二烯分子中含有两个双键，在不同条件下聚合时, 会产生结构不同的聚合物异构体，结构十分复杂，作为橡胶主要有三种结 构：顺式-1，4-聚异戊二烯，反式-1，4-聚异戊二烯, 3,4聚异戊二烯。戊二烯的分子量见为(32-62)×104。玻璃化温度因结构不同而异，钛系异戊橡胶的Tg为-70～-68℃，锂系异戊橡胶的Tg为-69～-66℃．反式1，4-聚异戊二烯的Tg为-60～-53℃。聚异戊二烯橡胶的结构与天然橡胶类似，故主要的物理机械性能接近天然橡胶，但因二者在微观结构、分子结构及极性基团等方面存在着一定差异，致使在物理机械性能和化学性质上呈现明显差别。聚异戊二烯橡胶的生胶强度显著低于天然橡胶，另外，聚异戊二烯的粘接性、弹性模量、撕裂强度、高温强度、耐磨性、疲劳寿命都不如天然橡胶。聚异戊二烯橡胶具有较高的弹性、较好的耐寒性。
