Abstract
A seal for a galvanic 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 seal has several advantageous over conventional galvanic cell seals, including better processability, and improved chemical resistance to alkaline medium.
