Patent ID: 7300903

Claim:
A process for olefin polymerization, comprising: polymerizing or copolymerizing an olefin in the presence of an olefin polymerization catalyst, the olefin polymerization catalyst comprising: (A) a transition metal compound represented by the following formula (I), 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: wherein M is a transition metal atom of Group 3 to Group 8, Group 10 or Group 11 of the periodic table, m is an integer of 1 to 3, R 1 to R 2 are the same or different, and are each a hydrogen atom, a halogen atom, a hydrocarbon group, a heterocyclic compound residue, an oxygen-containing group, a nitrogen-containing group, a boron-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, when m is 2 or greater, two of the groups R 1 to R 6 may be bonded to each other, with the proviso that the groups R 1 are not bonded to each other, n is a number satisfying the valence of M, 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 residue, a silicon-containing group, a germanium-containing group or a tin-containing group, and when n is 2 or greater, plural groups X may be the same or different and may be bonded to each other to form a ring.
