- 1 - HOE 88/F 061 Abstract Process for the preparation of a 1-olefin polymer A very efficient catalyst sy tem 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 linXed to one another by a -R6m-R5-R7n- bridge containing a hetexo atom and consisting of one or several members. The catalyst system, produces polymers having a high molecular weight and excellent grain morphology.
