PROCESS FOR THE PREPARATION OF A POLYOLEFIN

Olefins of the formula R11-CH=CH-R12 (R11 and R12=H or C1-C14-alkyl) are polymerized in the presence of a catalyst comprising at least one metallocene of the formula I (I) (M=zirconium or hafnium) and an aluminoxane, giving polymers of high molecular weight in high yield.
