Abstract:
THERE ARE DISCLOSED VULCANIZABLE, SUBSTANTIALLY LINEAR, SUBSTANTIALLY AMORPHOUS, HIGH MOLECULAR WEIGHT COPOLYMERIZATES OF ETHYLENE AND/OR A HIGHER ALPHA-OLEFIN HAVING THE GENERAL FORMULA CH2=CH-R IN WHICH R IS AN ALKYL GROUP CONTAINING 1 TO 6 CARBON ATOMS, AND POLYALKENYLCYCLOALKANES CONTAINING 3 TO 4 CARBON ATOMS IN THE CYCLE.
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.
