    摘要: A process is described whereby homopolymers and copolymers of isobutylene are prepared by effecting the polymerization at a temperature in the range of -100.degree. to 30.degree. C in the presence of a catalyst system including:(a) a compound selected from the group consisting of: AlCl.sub.3, AlBr.sub.3, AlEtCl.sub.2, TiCl.sub.4, SnCl.sub.4, SiCl.sub.4, VCl.sub.4, BF.sub.3, Al.sub.2 Et.sub.3 Cl.sub.3, SbCl.sub.5, SbF.sub.5, FeCl.sub.3, VOCl.sub.3, ZrCl.sub.4, AlI.sub.3, GaCl.sub.3 ; and(b) a compound adapted to react with the compounds of group (a) and selected from the group consisting of: SnR.sub.4, SnRX.sub.3, SrR.sub.4, TiX.sub.2 (OR).sub.2, Ti(OR).sub.4, PbR.sub.4, Ti(OR)X.sub.3, VO(OR).sub.3, Ti(OR).sub.3 X, (C.sub.5 H.sub.5).sub.2 Ti(C.sub.6 H.sub.5).sub.2, (C.sub.5 H.sub.5).sub.2 Ti(CH.sub.3).sub.2, Ti(Acac).sub.4, SnCl.sub.2 (acetate).sub.2 in which R is a hydrocarbon radical with from 1 to 10 carbon atoms and X is a halogen atom.The process is of particular value in the production of butyl rubber through the copolymerization of isobutylene and isoprene.
