Abstract: The invention relates to the production of highly reactive isobutylene homo- or copolymers with Mn = 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+]m+1 [R1R2R3B-(-Am+-BR5R6-)n-R4](m+1)- Lx (I), in which: R1 to R6 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 C1 to C18 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.

Abstract: The invention relates to a solvent-stable metal catalyst having slightly co-ordinating counter anions of formula I [M(L)a(Z)b]m+ m(A-) (I), wherein M represents a transition metal of groups 3 - 12 of the periodic system, a lanthanide or a metal of groups 2 or 13 of the periodic system; L represents a solvent molecule; Z represents a mono or polycharged ligand; A- represents a slightly or non co-ordinated anion; a represents a whole number which is greater than or equal to 1; b represents a whole number which is greater than or equal to 1, whereby the total from a and b is between 4 and 8, and m represents a whole number from 1 6. The invention also relates to a method for polymerising olefinically unsaturated compounds in the presence of said catalyst and copolymers which are made of monomers comprising isobutene and at least one vinylaromatic compound which is obtained according to said inventive method.

Abstract: The invention relates to a method for producing copolymers made from isobutene and at least one vinylaromatic component. Said method consists of polymerising isobutene or a hydrocarbon mixture containing isobutene with at least one vinylaromatic compound in the presence of a solvent-stable transistion metal complex comprising slightly co-ordinating anions as a polymerisation catalyst. The invention also relates to copolymers made of isobutene and at least one vinylaromatic compound, which can be obtained by means of said inventive method, in addition to specific functionalisation products therefrom.
