Improved process for preparation of butyl rubber utilizing activated alkylaluminum halides |
| abstract |
A process for preparing a butyl polymer having a weight average molecular weight of at least about 400,000. The process comprises the step of contacting a C4 to C8 monoolefin monomers with a C4 to C14 multiolefin monomer at a temperature in the range of from about -100°C to about +50°C in the presence of an aliphatic hydrocarbon diluent and a catalyst mixture comprising a major amount of a dialkylalumium halide, a minor amount of a monoalkylaluminum dihalide, and a minute amount of at least one of a member selected from the group comprising water, aluminoxane and mixtures thereof. |
