Ring-opened dimethylnorbornene and isopropylnorbornene copolymers

摘要

Dimethylnorbornene, isopropylnorbornene or a mixture thereof is copolymerized by ring opening with (1) at least one acyclic monoolefin or nonconjugated acyclic olefin and (2) optionally, dicyclopentadiene. The copolymers are thermo plastics which can be calendered and thermoformed, for example, to make rigid automotive goods such as glovebox covers, hubcaps and the like.
