Abstract
Vulcanizable amorphous linear terpolymers are obtained by copolymerizing two monoolefins and a divinyl hydrocarbon of formula CH2=CH-R-CH=CH2 where R is a plain or substituted aromatic ring or a cycloparaffinic ring. In the examples, ethylene, propylene and divinyl benzene (a mixture of o- and p-) are copolymerized in n-heptane or toluene solution in the presence of a catalyst comprising VCL4 and either HBrAIN(CH3)2 or H2AIN(CH3)2. Other divinyl hydrocarbons are also specified. The catalyst may be preformed or prepared in situ. The terpolymers are vulcanized using conventional methods.
