MODIFIED THERMOPLASTIC NORBORNENE POLYMER AND PROCESS FOR THE PRODUCTION THEREOF

摘要

A modified thermoplastic norbornene polymer produced by grafting a norbornene addition polymer with at least one unsaturated compound selected from the group consisting of unsaturated epoxy compounds and unsaturated carboxylic acid compounds, wherein the rate of modification by grafting with an unsaturated epoxy compound is 3 to 50 mole % or that with an unsaturated carboxylic acid compound is 7 to 50 mole %, and the number-average molecular weight (Mn) is 500 to 500,000; a process for the production of the same; and a cross-linkable polymer comprising the modified thermoplastic norbornene polymer and a cross-linking agent.
