Title:
【発明の名称】高分子量オレフィンポリマーの製造方法
Document Type and Number:
Japanese Patent JP3362153
Kind Code:
B2
Abstract:
A very effective catalyst system for olefin polymerisation consists of an aluminoxane and of a metallocene of the formula I in which, preferably, M<1> is Zr or Hf, R<1> and R<2> are alkyl or halogen, R<3> and R<4> are hydrogen, R<5> and R<6> are alkyl or haloalkyl, -(CR<8>R<9>)m-R<7>-(CR<8>R<9>)n- is a chain with one or more members in which R<7> can also be a (subst.) hetero atom and m+n is zero or 1. The catalyst system provides polymers with high molecular mass and high stereospecificity.
