Catalyst component for addition polymerization, process for producing catalyst for addition polymerization and process for producing addition polymer

摘要

There are provided: (I) a catalyst component for addition polymerization comprising: (i) a transition metal compound having (a) two cyclopentadiene type anion skeleton-carrying groups, which are linked with each other directly or through a bridging group, and (b) a hafnium atom as its central metal, and (ii) a transition metal compound having (a) two substituted cyclopentadiene type anion skeleton-carrying groups, which are not linked with each other, and (b) a zirconium atom or a titanium atom as its central atom; and (II) a process for producing a catalyst for addition polymerization, which comprises the step of contacting the above catalyst component with a co-catalyst component for activation.
