Abstract: Embodiments of the present disclosure are directed to methods for producing ethylene acid copolymer comprising: polymerizing via free-radical polymerization at a pressure of at least 1000 atmospheres (atm) an ethylene monomer and unsaturated carboxylic acid containing comonomer to produce the ethylene acid copolymer, wherein the ethylene monomer and unsaturated carboxylic acid containing comonomer are in a mixture comprising at least one saturated carboxylic acid cosolvent, and wherein the at least one saturated carboxylic acid cosolvent having a boiling point less than 237° C. at 1 atm pressure and is present in the mixture at an amount of 1 to 25 wt. %.
