    摘要: A process for the preparation of an olefin homopolymer or copolymer comprising polymerising at least one C2-20-α-olefin in slurry phase in the presence of 1) a metallocene compound of formula I: (Cp) (Cp″) RnMX2 (I) wherein: Cp is an optionally substituted and/or optionally fused homo- or heterocyclopentadienyl ligand; Cp″ is a cyclopentadienyl substituted by at least one C1-20-alkyl group; R is a bridge of 1-7 bridging atoms; M is a group 4 to 6 transition metal; each X is —CH2—Y, wherein Y is C6-20-aryl, C6-20 heteroaryl, C1-20-alkoxy, C6-20-aryloxy, —NR′2, —SR′, —PR′3, —SiR′3, —OSiR′3 or halogen; R′is C1-20-hydrocarbyl or in case of —NR′2, the two substituents R′ can form a ring together with the nitrogen atom wherein they are attached to; and each non-cyclopentadienyl ring moiety can further be substituted; n is 0 or 1; and (11) an aluminoxane.
