    • A thermosetting unsaturated polyester resin (UPR) composition comprising an unsaturated polyester polymer having at least two strained cycloolefinic double bonds and optional unstrained cycloolefinic double bonds, which can be cross-linked through a ring-opening metathesis polymerization (ROMP) or combination of ROMP and cationic or free radical polymerization is provided. No styrene is used in the resin composition. The thermosetting unsaturated polyester resin composition also comprises a catalyst system for the ring-opening metathesis polymerization, and in embodiments, can further comprise one or more optional unsubstituted or substituted cycloolefin monomer containing unsaturation, an optional co-catalyst selected from a cationic initiator or free radical initiator, and optional additives. The cured resin properties can be controlled through adjusting the structure and properties of the unsaturated polyester resin.
    • 一种热固性不饱和聚酯树脂(UPR)组合物,其包含具有至少两个应变环烯烃双键的不饱和聚酯聚合物和任选的非限制性环烯烃双键,其可以通过开环易位聚合(ROMP)或ROMP和 提供阳离子或自由基聚合。 在树脂组合物中不使用苯乙烯。 热固性不饱和聚酯树脂组合物还包括用于开环易位聚合的催化剂体系,并且在实施方案中可进一步包含一种或多种任选的不饱和的未取代或取代的环烯烃单体,任选的助催化剂,其选自阳离子引发剂或游离 自由基引发剂和任选的添加剂。 可以通过调节不饱和聚酯树脂的结构和性能来控制固化的树脂性能。
