MODIFIED THERMOPLASTIC NORBORNENE POLYMER AND PROCESS FOR THE PRODUCTION THEREOF

摘要

A modified thermoplastic norbornene polymer which is prepared by grafting a thermoplastic norbornene polymer selected from among open-ring polymers of norbornene monomers and hydrogenated derivatives thereof with at least one unsaturated compound selected from the group consisting of unsaturated epoxy compounds and unsaturated carboxylic acid compounds and which has a graft ratio of at least 10 mole % and a number-average molecular weight (Mn) of 500 to 500,000; a process for the production of the same; and a cross-linkable polymer composition comprising the modified thermoplastic norbornene polymer and a cross-linking agent.
