Abstract
A gasket for an electrochemical cell is formed of a styrenic polymer blend including a styrenic polymer and an impact modifying agent which increases the toughness of the styrenic polymer. The styrenic polymer based gasket has several advantages over conventional nylon gaskets, including better processability, and improved chemical resistance to alkaline medium.
