At least one alkylnorbornene, wherein the alkyl group contains from 8 to 12 carbon atoms, is copolymerized by ring opening with (1) at least one acyclic monoolefin or nonconjugated acyclic olefin and (2) optionally, dicyclopentadiene. These copolymers have substantially lower glass transition temperatures than lower alkylnorbornene copolymers and can be injection molded to make appliance housings and the like, or calendered and thermoformed to make, for example, automotive goods such as glovebox covers and the like.
至少一种烷基去氢甲基环戊烯,其中烷基含有8至12个碳原子,通过环开合与(1)至少一种无环单烯或非共轭无环烯烃和(2)可选地,二环戊二烯共聚。这些共聚物的玻璃化转变温度明显低于低烷基去氢甲基环戊烯共聚物,并可注塑成家电外壳等,或经过压延和热成型制成汽车用品,例如手套箱盖等。
