Beschreibung
Zusammenfassung:	A process for the preparation of an olefin homopolymer or copolymer comprising polymerising at least one C2-20-alpha- 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 (II) an aluminoxane.
