Abstract:
An olefin polymerization catalyst comprising:(A) a transition metal compound which is obtained by a bond-forming reaction of a compound represented by the following formula (a) with a metallic compound represented by the following formula (e) and in which the molar ratio of ligands to metal atoms is in the range of 1 to 6, said ligands being derived from the compound of the formula (a) and bonded to said metal atoms; â€ƒwherein A is an oxygen atom, a sulfur atom, a selenium atom or a nitrogen atom having bonded to it a group â€”R5, D is â€”C(R7)(R8)â€”, â€”Si(R9)(R10)â€”, â€”P(O)(R11)â€”, â€”P(R12)â€”, â€”SOâ€” or â€”Sâ€”, Z is a group bonded to N and represents â€”R13R14, &boxH;C(R15)R16 or &boxH;NR17, and R1 to R5 and R7 to R17 are the same or different and are each a hydrogen atom, a halogen atom, a hydrocarbon group, a heterocyclic compound residual group, an oxygen-containing group, a nitrogen-containing group, a boron-containing group, an aluminum-containing group, a sulfur-containing group, a phosphorus-containing group, a silicon-containing group, a germanium-containing group or a tin-containing group, and two or more of them may be bonded to each other to form a ring; MXkâ€ƒâ€ƒ(e) â€ƒwherein M is a transition metal atom of Group 3 to Group 9 of the periodic table, palladium or Group 11 of the periodic table, k is a number satisfying the valence of M to make the compound neutral, and X is a hydrogen atom, a halogen atom, a hydrocarbon group, an oxygen-containing group, a sulfur-containing group, a nitrogen-containing group, a boron-containing group, an aluminum-containing group, a phosphorus-containing group, a halogen-containing group, a heterocyclic compound residual group, a silicon-containing group, a germanium-containing group or a tin-containing group, and when k is 2 or greater, plural groups X are the same or different, and may be bonded to each other to form a ring; and (B) at least one compound selected from the group consisting of: (B-1) an organometallic compound, (B-2) an organoaluminum oxy-compound, and (B-3) a compound which reacts with the transition metal compound (A) to form an ion pair.
