PROBLEM TO BE SOLVED: To provide a norbornene-based copolymer which is used for various applications requiring polarity. SOLUTION: The polar group-containing cycloolefin-based copolymer contains 50-99.9 mol% of a cycloolefin and 0-49.9 mol% of an alkenyl unit and has a weight average molecular weight of 1,000-1,000,000. The alkenyl unit has a polar group at the terminal of the side chain. COPYRIGHT: (C)2006,JPO&NCIPI
