| titleOfInvention | Improved process for the production of butyl rubber using activated alkylaluminum halides. |
| abstract | PROBLEM TO BE SOLVED: To produce a butyl rubber polymer having an average molecular weight of more than 400,000 with a good change rate of isobutylene in an easily controlled method in which a low-cost inert aliphatic hydrocarbon solvent can be used without using methyl chloride. Providing a way to do it. A process for producing a butyl polymer having a weight average molecular weight of at least about 400,000. This method includes an aliphatic hydrocarbon diluent and a catalyst mixture comprising a large amount of dialkylaluminum halide, a small amount of dialkylaluminum dihalide, and a compound selected from the group consisting of trace amounts of water, aluminoxane and mixtures thereof. is, consist contacting at a temperature in the range of about -100 to about + 50 ℃ a C 4 -C 8 monoolefin monomer with C 4 -C 14 multi-olefin monomer. [Selection figure] None |
