Abstract

A catalyst system for the polymerization of olefins is prepared by initially charging one or more compounds of the formula I a or I b, subsequently adding a molecularly defined activator of the formulae II a to c[(L—H)]+[(M′)Q1Q2Q3Q4]−  II a[(CAr3)]+[(M′)Q1Q2Q3Q4]−  II b[(M′)Q1Q2Q3]  II cand finally adding an alkylating agent selected from among LiR11, MgR11R12 and AlR12R13R14.
