ABSTRACT:
The invention relates to polymeric resin blends containing polyelectrolyte resins blended into a polymer or copolymer matrix. Specifically, the polyelectrolyte resins are (co)polymers without hydrolyzable groups. The matrix polymer is a tough, and highly chemical-resistant (co)polymer, preferably a fluoropolymer. The polymeric resin blend is useful for forming films, and especially films useful for MEAs for use in fuel cells.
