Title: PRODUCTION METHOD FOR ETHYLENE-BASED IONOMER AND ETHYLENE-BASED IONOMER
Abstract:
The purpose of the present invention is to provide a production method for a novel ethylene-based ionomer exhibiting exceptionally excellent break elongation, breaking stress, and strain hardening and a high melting point, as well as excellent mechanical properties and heat resistance. This invention pertains to an ethylene-based ionomer production method characterized by including a heating and conversion step in which a specific ethylene/unsaturated carboxylic acid ester copolymer is heated and an ester group in the copolymer is converted to a metal-containing carboxylic acid salt containing a metal ion from group 1, group 2 or group 12 of the periodic table.
