Abstract: The invention relates to a catalyst complex comprising boron trifluoride and a co-catalyst mixture of 10 to 90 wt% of a monovalent primary C1 to C20 alcohol and 90 to 10 wt% of a monovalent secondary C3 to C20 alcohol, wherein the molar ratio of boron trifluoride to the sum of all alcohols is 2:1 to 1:10. Said catalyst complex is used in the production of highly reactive isobutene homopolymers having a number-average molecular weight of 300 to 50,000, wherein a C4 hydrocarbon mixture containing at least 20 wt% of isobutene and in total at least 10 wt% of other C4 olefins is used as a feed material.

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.
