- 1 - HOE 89/F 291 Abstract of the disclosure: A process for the preparation of a polyolefin wax If a catalyst consisting of an aluminoxane and a metal- locene of the formula I (I) Image in particular R5R6C (Ind)2 or R5R6C (Ind)2 Zr(CH3)2, is employed for the polymerization of olefins of the formula R9CH = CHR10 (R9, R10 = H or C1-C28 alkyl), the isotacticity of the polymer wax and hence the hardness and melting point can be varied simply by changing the polymerization tempera- ture, without the molecular weight of the polymer being noticeably changed at the same time.
