Abstract
There is disclosed a new class of substantially linear, amorphous, unsaturated, vulcanizable, high molecular weight copolymers of ethylene, a higher alpha-olefin of the formula CH.sub.2 = CHR in which R is an alkyl group containing from 1 to 6 carbon atoms and certain specific omega-alkenyl derivatives of norbornene in which the double bond of the alkenyl group is non-vinyl and occurs at either end of said group. A process for the preparation of the new copolymers by the use of catalysts acting according to an anionic coordinate mechanism is also disclosed.
