Abstract (en)

[origin: WO2007057404A1] The invention relates to the production of highly reactive isobutylene homo- or copolymers with M<SUB>n</SUB> = 500 to 45,000 by polymerizing isobutylene in liquid phase in the presence of a dissolved, dispersed or supported boron-containing catalyst complex by using, as a catalyst complex, a Bronsted compound (I) [H<SUP>+</SUP>]<SUB>m+1</SUB> [R<SUP>1</SUP>R<SUP>2</SUP>R<SUP>3</SUP>B-(-A<SUP>m+</SUP>-BR<SUP>5</SUP>R<SUP>6</SUP>-)<SUB>n</SUB>-R<SUP>4</SUP>]<SUP>(m+1)-</SUP> L<SUB>x</SUB> (I), in which: R<SUP>1</SUP> to R<SUP>6</SUP> represent aliphatic, heterocyclic or aromatic fluorine-containing hydrocarbon radicals, which are independent of one another and which each have 1 to 18 carbon atoms or silyl groups containing C<SUB>1</SUB> to C<SUB>18</SUB> hydrocarbon radicals; A represents a bridge member that, via its nitrogen atoms forms bonds which are covalent to the boron atoms; L represents neutral solvent molecules; n = 0 or 1; m = 0 or 1, and; x = 0.
