PROBLEM TO BE SOLVED: To provide a cyclic olefin copolymer having excellent optical properties, high adhesiveness and adhesion to other materials, low hygroscopicity, high heat resistance, and low or no odor. Provided are a polymer, a method for producing the polymer, and a thermoplastic polymer composition. SOLUTION: A structural unit derived from ethylene and a general formula (1) wherein X 1 to X 2 are H, a hydrocarbon group or the following functional group; One is a functional group. Z 1 to Z 2 are H or a hydrocarbon group having 1 to 10 carbon atoms, and those bonded to a carbon atom to which a functional group is bonded are hydrocarbon groups. n is an integer of 0-2. Functional group: -OH, hydrocarbon group containing it, -COOH, hydrocarbon group containing it, A primary or secondary amino group, a hydrocarbon group containing an amino group, a quaternary ammonium salt thereof, an amide group having N active hydrogen, a hydrocarbon group to which this is bonded, or X 1 and X 2 An imide group represented by -CO-NH-CO-. And a structural unit derived from a specific cyclic olefin. Embedded image |
