RING-OPENED ALKYLNORBORNENE COPOLYMERS

RING-OPENED ALKYLNORBORNENE COPOLYMERS

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 temper...

Zusammenfassung: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.
