    Abstract: Continuous production of polyisobutylene having a content of terminal double bonds of greater than 50% by polymerization of isobutene in the presence of a polymerization catalyst usual therefor, by combining a technical 1-butene-, 2-butene- and isobutene-containing C4 hydrocarbon stream together with a stream of pure isobutene, and feeding the combined stream into the reaction zone in such a manner that the steady state concentration of isobutene in the combined stream at the point where the combined stream is fed into the reaction zone has a value of on average at least 40% by weight, and the invention also relates to a polymerization system therefor.

    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.
