Abstract: Continuous preparation of polyisobutylene having a content of terminal double bonds of more than 50% by polymerizing isobutene in the presence of a polymerization catalyst customary therefor, by combining a technical 1-butene-, 2-butene- and isobutene-containing C4 hydrocarbon stream together with a stream of pure isobutene and feeding them into the reaction zone in such a way that the steady-state concentration of the isobutene in the combined stream at the feed point of the combined stream into the reaction zone has an average value of at least 40% by weight, and a polymerization plant therefor.

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.
