PROCESS FOR THE PREPARATION OF A POLYOLEFIN |
| 摘要 |
Process for the preparation of a polyolefin Olefins of the formula R11-CH=CH-R12 (R11, R12 = H or C1-C14-alkyl) are polymerized in the presence of a catalyst consisting of at least one metallocene of the formula I (M = zirconium or hafnium) and an aluminoxane. Polymers having a high molecular weight are obtained in a high yield.
