NORBORNENE-BASED RING-OPENING POLYMERIZATION POLYMER, PRODUCT OF HYDROGENATION OF NORBORNENE-BASED RING-OPENING POLYMERIZATION POLYMER, AND PROCESSES FOR PRODUCING THESE

摘要

A norbornene-based ring-opening polymerization polymer which in the molecule has repeating units represented by the formula (1): (1) [wherein R<1> represents Q; R<2> represents Q or C(=O)R<5>; R<3> represents Q or C(=O)R<6>; R<4> represents Q or X-C(=O)R<7>; Q represents hydrogen, a C1-10 hydrocarbon group, etc.; R<5>, R<6>, and R<7> each represents hydroxy, C1-10 alkoxy, etc., provided that R<6> and R<7> may be bonded to each other to constitute oxygen, NH, etc.; X represents methylene, etc.; provided that when R<2> is Q, then R<3> is C(=O)R<6> and R<4> is X-C(=O)R<7> and that when R<4> is Q, then R<2> is C(=O)R<5>, R<3> is C(=O)R<6>, and the configuration of R<2> and R<3> is trans; and m is 0 or 1] and which has a weight-average molecular weight as determined by gel permeation chromatography of 1,000 to 1,000,000. Also provided is a product of hydrogenation of the norbornene-based ring-opening polymerization polymer. The norbornene-based ring-opening polymerization polymer and the hydrogenation product are excellent in heat resistance, electrical properties, etc.
