Abstract
Disclosed in embodiments herein are ionomers and methods of making the same. The ionomers comprise a neutralized blend of olefin-carboxylic acid copolymers and Group II, Group IIIA, and transition metal salts. The method includes mixing an acid copolymer formed from an α-olefin monomer and an α,β-ethylenically unsaturated carboxylic acid having at least one carboxylic acid group with an amine-containing aqueous solution to form an aqueous dispersion containing an amine salt of the acid copolymer. The method further includes mixing a solution of a Group IIA , Group IIIA, or transition metal salt with the aqueous dispersion containing the amine salt of the acid copolymer to exchange at least a portion of the amine salt for the Group IIA , Group IIIA, or transition metal salt, thereby forming the ionic copolymer.
