  • Polysulfide-epoxy thermoplastic elastomers
    Patent number: 5610243
    Abstract: A thermoplastic elastomer is made by the reaction of an epoxy resin with a liquid mercapto-terminated polysulfide wherein the ratio of epoxy equivalents in the epoxy resin to mercapto equivalents is from about 0.6 to about 0.98, with the proviso that when the ratio is greater than about 0.95:1, the polysulfide is further reacted with an amount of a mono-epoxy compound sufficient to raise the ratio of total epoxy equivalents to mercapto equivalents to a maximum of 1:1. An elastomer having residual --SH groups is air-curable. The elastomer is useful as a hot melt sealant for insulated window units.
