Abstract (en)
[origin: WO2007057406A1] The invention relates to the production of highly reactive isobutylene homo- or copolymers with M<SUB>n</SUB> = 500 to 1,000,000 by polymerizing isobutylene from technical flows of C<SUB>4</SUB>-hydrocarbon having a isobutylene content ranging from 1 to 90 % by weight in liquid phase in the presence of a dissolved, dispersed or supported catalyst complex by using, as a catalyst complex, a Bronsted acid compound (I) [H<SUP>+</SUP>]<SUB>k</SUB> Y<SUP>k-</SUP> L<SUB>x</SUB> (I) Y<SUP>k-</SUP> weakly coordinating k-valent anion, which contains at least one carbon-containing grouping; L represents neutral solvent molecules, and; x = 0.
