摘要： The present invention relates to a process for preparing high- reactivity isobutene homo- or copolymers with a content of terminal vinylidene double bonds per polyisobutene chain end of at least 70 mol%, which comprises polymerizing isobutene or an isobutene-comprising monomer mixture in the presence of an aluminum trihalide-donor complex effective as a polymerization catalyst or an alkylaluminum halide-donor complex effective as a polymerization catalyst, wherein the aluminum trihalide or alkylaluminum halide is treated with at least one inorganic hydrate.

摘要： The present invention relates to a process for preparing high-reactivity isobutene homo- or copolymers with a content of terminal vinylidene double bonds per homo- or copolymer chain end of at least 70 mol % which comprises polymerizing isobutene or an isobutene-comprising monomer mixture in the presence of an aluminum trihalide-donor complex effective as a polymerization catalyst or of an alkylaluminum halide-donor complex, said complex comprising, as the donor, a mixture of at least two organic compounds with at least one ether function each.

摘要： The invention relates to the production of highly reactive isobutene homo or copolymers having a content of vinylidene double bonds per polyisobutene chain termination of at least 50 mol % and a polydispersity of preferably 1.05 to less than 3.5, wherein isobutene or a monomer mixture containing isobutene is polymerized in the presence of an aluminum trihalogenide donor complex acting as a polymerization catalyst, in particular an aluminum trichloride donor complex, comprising an organic compound having at least one ether function or a carboxylic acid ester function as the donor.
