- 1 - HOE 88/F 060 Abstract Process for the preparation of 1-olefin polymers A very efficient catalyst system for the polymerization of 1-olefins consists of an aluminoxane and a metallocene which is a compound of the formula I (I) Image in which R1 and R2 denote hydrogen atoms, halogen atoms or hydro- carbon radicals and R3 and R4 are mononuclear or poly- nuclear hydrocarbon radicals which can form a sandwich structure with the central atom and which are linked to one another by a -R3m-R5-R7n- bridge containing a hetero atom and consisting of one or several members. The catalyst system produces polymers having a high molecular weight.
