Polymer blends comprising polyethylene (meth) acrylic acid ionomers and boronic ester crosslinkers

Abstract

Described in embodiments herein are polymer blends that may comprise a partially neutralized polyethylene (meth) acrylic acid ionomer and a boronic ester crosslinker comprising a Lewis acid with an accept number greater than 16.7, as determined by Gutmann-Beckett method. The polymer blend may comprise from 90 weight percent (wt. %) to 99 wt. % of the partially neutralized polyethylene (meth)acrylic acid ionomer, and from 1 wt. % to 10 wt. % of the boronic ester crosslinker, based on the total weight of the polymer blend. A process of manufacturing a molded article having improved heat resistance is disclosed herein, which may comprise melt mixing the partially neutralized polyethylene (meth)acrylic acid ionomer and the boronic ester crosslinker to form the polymer blend and molding the polymer blend into a molded article.
