PROCESS FOR PREPARING HIGH-REACTIVITY ISOBUTENE HOMO- OR COPOLYMERS

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.
