Abstract: Preparation of isobutene homopolymers having a weight-average molecular weight of 75 000 to 10 000 000 by polymerization of isobutene, by (a) performing the polymerization at -80°C to -190°C, (b) using, as an inert solvent, optionally halogenated C1 to C5 hydrocarbons, (c) using, as a polymerization catalyst, a Lewis acid complex, (d) performing the polymerization in the presence of at least one reaction accelerator in the form of an ethylenically saturated hydrocarbon compound comprising one oxygen atom and no abstractable proton, and (e) performing the polymerization in the presence of at least one chain length regulator comprising one tertiary olefinic carbon atom.

Abstract: 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.

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: Preparation of polyisobutylene having a content of terminal double bonds of more than 50% by polymerizing isobutene using a polymerization catalyst customary therefor from a technical 1-butene-, 2-butene- and isobutene-containing C4 hydrocarbon stream which may comprise up to 3000 ppm by weight, of 1,3-butadiene, by reducing the content of oxygenates in the C4 hydrocarbon stream before the polymerization of the isobutene by contacting it with an inorganic adsorbent at a pressure of from 1 to 20 bar and a temperature of from 20 to 220° C.

Abstract: A polyisobutylene having a total content of vinylidene double bonds of more than 50 mol % and a number-average molecular weight of 500 to 10 000 daltons, where at least 10% of all the vinylidene double bonds in the polyisobutylene are part of one or more side chains composed of at least 2 carbon atoms from the main polyisobutylene chain. Such a polyisobutylene is suitable for production of fuel and lubricant additives.
