    Abstract: The invention relates to a method for producing mainly ethylenically unsaturated isobutene polymers, wherein the sum of proportions of molecules with a double bond in an α position and molecules with a double bond in a position β is increased to 75 %mol by polymerising isobutene in a liquid phase in the presence of a diluted or dispersed catalyst complex which comprises (i) an electron donor and (ii) a compound of general formula (I) Ha Meb [MFx]c, wherein Me is a metal with oxidation state m, M is an element selected from elements of the groups 2, 3, 4, 5, 10, 11, 13, 14 or 15 of the periodic table according to the IUPAC notation of an element oxidation number n, a is an integer ≥1, b is an integer ≥0, x is an integer ≥2 and c is [(a+mb)/(x-n)]. The catalyst is preferably embodied in the form of HBF4 O(CH3)2. The inventive method makes it possible to obtain an isobutene polymer having a low fluorine-content even using technical C4 hydrocarbon portions as an isobutene source.

    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.
