Abstract

The invention relates to the production of isobutylene homopolymers having a weight-average molecular weight of 75,000 to 10,000,000 by means of the polymerization of isobutylene by (a) performing the polymerization at -80?C to - 190?C, (b) using optionally halogenated C1 to C5 hydrocarbons as an inert solvent, (c) using a Lewis acid complex as a polymerization catalyst, and (d) performing the polymerization in the presence of at least one reaction accelerator in the form of an ethylenically saturated hydrocarbon compound, which contains an oxygen atom and no proton that can be emitted, and performing the polymerization in the presence of at least one chain length regulator, which contains a tertiary olefinic carbon atom.
