| abstract |
A process for preparing a polymer containing derived units of one or more alpha olefins of formula CH2=CHW wherein W is a C3-C10 hydrocarbon radical and optionally from 0 to 81 % by mol of derived units of propylene or 1-butene, comprising contacting under polymerization conditions one or more alpha olefins of formula CH2=CHW and optionally propylene or 1-butene in the presence of a catalyst system obtainable by contacting: a) a metallocene compound of formula (I) wherein M, X, L, T, R1, R2, R7 and R8 are described in the text; and (b) an alumoxane or a compound capable of forming an alkyl metallocene cation. |
