Method for the production of a catalyst system for the polymerisation of olefins

摘要

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.
