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, a co-initiator of organometal alkoxide halides, organometal phenoxide halides and/or organometal carboxyl halides is used to produce polymers particularly polyisobutylene and isobutylene/para-methyl-styrene copolymers.
