Patent ID: 6943227

Claim:
A method of polymerization of olefins, which comprises: copolymerizing ethylene and an α-olefin in the presence of a catalyst for olefin polymerization containing (A1) a hafnium compound or a zirconium compound having at least one conjugated 5-membered ring ligand, (A2) a zirconium compound having at least one conjugated 5-membered ring ligand having formula (5) below, but different from zirconium compound (A1), wherein, in formula (5), A and A′, which are the same or different, each represents a ligand having a conjugated 5-membered ring structure, and X and Y, which are the same or different, each represents a hydrogen atom, a halogen atom, a hydrocarbon group, an alkoxy group, an amino group, a phosphorus-containing hydrocarbon group, or a silicon-containing hydrocarbon group, which are bonded to Zr, and (B) a phyllosilicate.
