Potassium salt of dicyclopentadiene acid(DCPD(COOK)2), aderivative of cyclopertadiene was used as a crosslinking agent for thevulcanization of acrylic rubber(ACM) through esterification between thecrosslinking agent and active chlorine of ACM.

• 在高温时,DCPD 可以发生逆Diels-Alder 反应而解交联成 CPD,交联 ACM 变为线型分子,因而具有了加工流动性,降温后,两个CPD再双取成 DCPD,再度形成交联结构,赋予 ACM良好的力学性能。
