Catalyst for olefin polymerization, process for the polymerization of olefin, and transition metal compound employable for the catalyst

摘要

The catalyst for olefin polymerization of the present invention contains R1kR2lR3mM(SO3R4) (M=Zr, Ti or Hf; R1-3=a group having a cyclopentadienyl skeleton) as a catalyst component of a transition metal compound. According to the catalyst of the invention, an olefin polymer having excellent particle properties can be prepared with high polymerization activities, and further a copolymer having a narrow composition distribution can be prepared when two or more monomers are copolymerized. Of the above-mentioned transition metal compounds, a compound represented by the following formula is a novel compound unknown so far and shows excellent catalytic properties. (Cp=a group having a cyclopentadienyl skeleton, X=SO3R, a halogen atom, R, OR, NRn, S(O)qR, SiR3 or P(O)qR3, n=1, 2 or 3; q=0, 1 or 2)
