摘要:
The invention concerns 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: (A3) a reaction product of a compound of the formula MX k with a compound of the formula (III); or (A6) a compound of the formula (VI)
wherein M is transition metal atom selected from Group 5 of the periodic table k and n are a number satisfying the valence of M, and X is hydrogen, halogen, oxygen, a hydrocarbon group, a heterocyclic compound residual group, or a group containing O, S, N, B, Al, P, Si, Ge, Sn or halogen; if k is ≥ 2, the individual X may be the same or different, and plural groups X may be bonded to each other to form a ring; A is - O-, -S-, -Se- or -NR 26 -, and R 21 -R 28 each individually are H, halogen, a hydrocarbon group, a heterocyclic compound residual group, and a group containing O, S, N, B, Al, P, Si, Ge or Sn, and two or more of them may be bonded to each other to form a ring.

The present invention is intended to provide an olefin polymerization catalyst comprising a transition metal compound and having an excellent olefin polymerization activity and to provide a process for olefin polymerization using this catalyst. The olefin polymerization catalyst comprises a transition metal compound (A-2) represented by the formula (II-b) and further comprises at least one compound (B) selected from the group consisting of an organometallic compound (B-1), an organoaluminum oxy-compound (B-2) and a compound (B-3) which reacts with the transition metal compound (A-2) to form an ion pair.
(wherein M, m, A, R 1 , R 2 , R 7 - R 10 , n and X are further defined in the specification).

A novel olefin polymerization catalyst is provided which comprises (A) a transition metal compound or lanthanoid compound containing two or more atoms selected from the group consisting of boron, nitrogen, oxygen, phosphorus, sulfur, and selenium; and (B) a Lewis acid. A process for producing an olefin polymer is alsoprovided. The catalyst has a high olefin polymerization activity without a combined use of an expensive organoaluminum oxy-compound or organoboron compound, and can maintain the high activity for a long polymerization time.
