摘要：
An object of the present invention is to provide a novel production method of ethylene-based ionomer having excellent mechanical properties and heat resistance which exhibits remarkably excellent breaking elongation, breaking stress, and strain hardening, and has a high melting point. The present invention relates to a production method of an ethylene-based ionomer including a heating conversion step of heating a specific ethylene/unsaturated carboxylic acid ester copolymer and converting the ester group in the copolymer into a metal-containing carboxylate containing a metal ion of Group 1, 2, or 12 of the periodic table.
