CA 2071706

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. Image (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)
