(57) [Abstract] [Objective] To provide a catalyst component for obtaining a high melting point and high molecular weight α-olefin polymer in high yield, a catalyst, and a process for producing an α-olefin polymer using the same. thing. [Structure] An α-olefin polymerization catalyst component represented by the following compound [I], an α-olefin polymerization catalyst obtained by combining the components, and an α-olefin polymer production method using the catalyst. [Chemical 1] R 1 = H, C 1-6 hydrocarbon residue or C 1-12 Si-containing hydrocarbon group, R 2 and R 3 = divalent C 3-30 hydrocarbon group, C 1-30 and Si 1 to 6 Si-containing hydrocarbon groups, provided that at least one of R 2 and R 3 is the Si-containing hydrocarbon group, Q = divalent, C 1-20 hydrocarbon group, silylene group, C 1-20 carbon group. Hydrogen group-containing silylene group, germylene group, C 1-20 hydrocarbon group-containing germylene group, X and Y = H, halogen, C 1-20 hydrocarbon group, oxygen-containing C 1 to 20 hydrocarbon residues, M = IVB to VIB group transition metals. [Effect] The above object is achieved. |
