Patent number: 7629426Abstract: 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.Type: GrantFiled: June 18, 2008Date of Patent: December 8, 2009Assignee: Arkema Inc.Inventor: James T. Goldbach
