Patent ID: 7312284

Claim:
A process for producing a polar olefin copolymer comprising copolymerizing a non-polar olefin and a polar olefin in the presence of a catalyst comprising: (A4) a compound of a transition metal selected from Group 4 of the periodic table, which is represented by the following formula (IV): wherein M′ is a transition metal atom selected from Group 4 of the periodic table, m is 2, A is an oxygen atom, a sulfur atom or a selenium atom, or a nitrogen atom having a substituent R 6 , R 1 to R 4 and R 6 may be the same or different, they 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, two or more of them may be bonded to each other to form a ring, and when m is 2 or greater, one group of R 1 to R 4 and R 6 contained in one ligand and one group of R 1 to R 4 and R 6 contained in other ligands may be bonded, and R 1 s, R 2 s, R 3 s, R 4 s or R 6 s may be the same or different, n is a number satisfying a valence of M′, and X is a hydrogen atom, a halogen atom, an oxygen 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 n is 2 or greater, plural atoms or groups indicated by X may be the same or different, and plural groups indicated by X 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 (A4) to form an ion pair.
