| 摘要 |
<p>The invention relates to a process for the polymerisation of one or more α-olefins to form a polyolefin at a temperature above 100 °C with the aid of a catalyst system comprising a Zr metallocene, the Zr metallocene being a compound having the formule (I), in which R1 is, independently of one another, H, an alkyl group with 1-10 C atoms, an alkylaryl group with 7-20 C atoms or an aromatic group with 6-20 C atoms, R?2 and R3¿ are, independently of one another, H, an alkyl group with 1-10 C atoms, an alkylaryl group with 7-20 C atoms, an aromatic group with 6-20 C atoms or a silanylene group with 3-30 C atoms, n = 4 or 8.</p> |
