Metallocene catalysts containing an idenyl moiety substituted at the 4,-5,-6- or 7-position by a siloxy or germyloxy group
摘要:
A metallocene catalyst in which the metal is coordinated by a η5 cyclopentadienyl ligand which forms part of an indenyl or indenyloid moiety, characterized in that said moiety is directly or indirectly substituted at the 4-, 5-, 6- or 7-position by a pendant siloxy or germyloxy group.
