    • High Tg polymers prepared by metathesis ring-opening polymerization of N-aryl norbornene dicarboximide and one or more other norbornene derivative monomers, wherein said N-aryl group is substituted with a halo, cyano, alkyl or halogenated alkyl substituting group which is ortho or meta to the imide nitrogen. Preferred polymers with exceptionally high Tg are prepared from N-ortho substituted phenyl norbornene dicarboximide monomer. Mixtures of N-ortho substituted phenyl norbornene dicarboximide and N-meta substituted phenyl norbornene dicarboximide can exhibit eutectic melting points which facilitates melt polymerization.
    • 通过N-芳基降冰片烯二羧酰亚胺和一种或多种其它降冰片烯衍生物单体的复分解开环聚合制备的高Tg聚合物,其中所述N-芳基被卤素,氰基,烷基或卤代烷基取代基取代,其为邻位或间位 到酰亚胺氮。 具有特别高Tg的优选聚合物由N-邻位取代的苯基降冰片烯二甲酰亚胺单体制备。 N-邻位取代的苯基降冰片烯二甲酰亚胺和N-间位取代的苯基降冰片烯二羧酰亚胺的混合物可以表现出有利于熔融聚合的共晶熔点。
