  • MODIFIED THERMOPLASTIC NORBORNENE POLYMER AND PROCESS FOR THE PRODUCTION THEREOF
    Publication number: 20020103303
    Abstract: A modified thermoplastic norbornene polymer obtained by graft-modifying a thermoplastic norbornene polymer selected from a ring-opening polymer of a norbornene monomer or a hydrogenated product thereof with at least one unsaturated compound selected from the group consisting of unsaturated epoxy compounds and unsaturated carboxylic compounds, and having a rate of graft modification of at least 10 mol % and a number average molecular weight (Mn) of 500 to 500,000, a production process thereof, and a crosslinking polymer composition comprising the modified thermoplastic norbornene polymer and a crosslinking agent.
