More Information
Summary:The catalyst for olefin polymerization of the present invention contains R1kR21R3mM(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).
