(57) [Problem] To provide a polar group-containing olefin copolymer excellent in adhesion, compatibility, flexibility and the like to a metal or a polar resin. The olefin copolymer containing a polar group comprises the following structural units (1), (2), and (3), has a molecular weight distribution (Mw / Mn) of 3 or less, and is measured by a 13 C-NMR spectrum. The calculated intensity ratio (Tαβ / (Tαα + Tαβ)) is 1.0 or less; (Wherein R 1 and R 2 are different from each other and have 1 carbon atom To 18 aliphatic hydrocarbon groups or hydrogen atoms, R 3 is a hydrocarbon group, R 4 is a hetero atom or a group containing a hetero atom, r is 0 or 1, X is a hydroxyl group, a carboxylic acid group, a carboxylic ester group, an acid anhydride group, an amino group, an amide group, an epoxy group or a mercapto group, p is 1 to 3, and p is 2 or 3 In this case, X may be the same or different. ). |
