Abstract
A carbocationic catalyst composition comprising an initiator of water, a tertiary alkyl or aralkyl halide, ester, ether, carboxylic acid, acid halide or a polymeric halide and a co-initiator of an alkoxy metal halide, is used to produce narrow molecular weight distribution olefin polymers particularly isobutylene/para-methyl-styrene copolymers.
