| abstract |
Substantially linear, amorphous, unsaturated, high molecular weight copolymers of at least one monoolefin selected from ethylene and higher alpha-olefins, with 1, 4, 9-decatriene, alkyl, aryl, and arylalkyl-substituted 1, 4, 9-decatrienes, or 1, 5, 9-decatriene, are disclosed. The copolymers are sulfurvulcanizable to useful synthetic eleastomers. A process for obtaining the copolymers by copolymerizing a mixture of the selected monomers in contact with catalysts prepared from certain transition metal compounds and organometallic compounds or hydrides of Group I to III metals is also disclosed. |
