Abstract:
An olefin polymerization catalyst obtained by contacting:a transition metal compound (A) represented by the general formula (1) described below; an organoaluminumoxy compound (B) soluble in an aromatic solvent; and water (C), wherein the molar ratio of aluminum atom contained in the organoaluminumoxy compound (B) to a transition metal atom contained in the transition metal compound (A) is 1 to 20000, and the amount of water used is 0.1 to 3.0 mol per 1 mol of aluminum atom contained in the organoaluminumoxy compound (B), wherein M represents a transition metal atom of the Fourth Group of the Periodic Table, X and Y independently represent a hydrogen atom, a halogen atom, an alkyl group, an aryl group, an aralkyl group, an alkoxy group, an aryloxy group, an aralkyloxy group, a sulfonyloxy group, a di-substituted amino group or a substituted silyl group, R1, R2, R3, R4, R5, R6, R7 and R8 independently represent a hydrogen atom, an alkyl group, an aryl group, an aralkyl group, an alkoxy group, an aryloxy group, an aralkyloxy group, a di-substituted amino group or a substituted silyl group, R1, R2, R3, R4, R5, R6, R7 and R8 may be optionally bonded to form a ring, T represents a divalent covalent crosslinking group having 1 to 20 carbon atoms, or a divalent group represented by â€”Oâ€”, â€”Sâ€”, â€”Sâ€”Sâ€”, â€”S(&boxH;O)â€”, â€”S(&boxH;O)2â€”, â€”C(&boxH;O)â€”, â€”N(R9)â€”, â€”P(R9)â€” or â€”P(&boxH;O) (R9)â€”wherein R9 represents a hydrogen atom or a hydrocarbon group having 1 to 6 carbon atoms in each case, and n is an integer of from 0 to 3.
