SOLVENSSTABILISIERTE METALLKOMPLEXE MIT SCHWACH KOORDINIERENDEN GEGENANIONEN ALS POLYMERISATIONSKATALYSATOREN

The invention relates to a solvent-stable metal catalyst having slightly coordinating 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 sol...

description The invention relates to a solvent-stable metal catalyst having slightly coordinating 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 coordinated 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.
