降冰片烯及其衍生物开环易位聚合的研究进展

ADVANCES IN THE STUDY ON RING OPENING METATHESIS POLYMERIZATION OF NORBORNENE AND ITS DERIVATIVES

综述了降冰片烯 (NBE)及其衍生物开环易位聚合 (ROMP)的研究进展。分析了 ROMP反应特点、催化剂类型对于 NBE衍生物的 ROMP;由于聚合反应发生在 NBE环上 ,其衍生物上的取代基赋予了该聚合物特殊的功能 ,为合成大分子单体提供了一种新方法。还报道了 NBE的活性聚合研究。

The development of study on ring opening metathesis polymerization(ROMP) of norbornene(NBE) and its derivativesis reviewed with 30 references. The unique feature of this kind of polymerization is that the unsaturated carbon carbon double bonds and rings structure are remained in the polymer. W, Mo,Re, Ru, Ti, etc. halides and their organometallics are effective catalysts for NBE polymerization. The functional polymers can be obtained by ROMP of NBE derivatives, which are substituted by ester, fluoride, borane, silicane, etc. Some of these can be transformed into a variety of functionalities. The studies of living polymerization of NBE were also introduced.
