  • Gels comprising block copolymers
    Patent number: 5710206
    Abstract: A gel or gelloid composition contains (a) more than 50% by weight (based on total polymer content) of a block copolymer containing relatively hard blocks and relatively elastomeric blocks; (b) a polyphenylene ether; and (c) at least 500 parts by weight of an extender liquid per 100 parts by weight of the block copolymer, which liquid extends and softens the elastomeric blocks of the block copolymer. The polyphenylene ether is present in an amount sufficient to increase the softening or melting temperature of the gel or gelloid composition over that of the same composition without polyphenylene ether. The gel or gelloid composition is useful for sealing applications.
