High molecular weight ethylene / α-olefin / polar group-containing allylic monomer terpolymers having a novel structure that was difficult to synthesize by radical polymerization and other polymerization modes, and their production Providing a method. A terpolymer having monomer units represented by formulas (3), (4), and (5), which satisfies the following requirements (A), (B), and (C): Ternary copolymer and production method thereof. (A) Mw / Mn is 1.5 to 4.0. (B) (Mn) is 10,000 to 1,000,000. (C) The molar ratio 1 of the ethylene monomer unit and the molar ratio n of the α-olefin monomer unit satisfy the relationship of the following formula. {L / (l + n)} × 100 ≧ 60 [Selection figure] None |
