Abstract
A norbornene ring-opened polymer which in the molecule has repeating units represented by the formula (1):wherein Rrepresents Q, Rrepresents Q or C(═O)R, Rrepresents Q or C(═O)R, and Rrepresents Q or X—C(═O)R(wherein Q represents hydrogen, a Chydrocarbon group, etc.; R, Rand Reach represents hydroxyl, Calkoxyl, etc., provided that Rand Rmay be bonded to each other to constitute oxygen, NH, etc.; X represents methylene, etc., provided that when Ris Q, then Ris C(═O)Rand Ris X—C(═O)Rand that when Ris Q, then Ris C(═O)R, Ris C(═O)R, and the configuration of Rand Ris trans, and m is 0 or 1), the polymer having a weight-average molecular weight as determined by gel permeation chromatography of 1,000 to 1,000,000. Also provided is a hydrogenation product of the norbornene ring-opened polymer. The norbornene ring-opened polymer and the hydrogenation product are excellent in heat resistance, electrical properties, etc.
