  • Thermoplastic compositions with modified electrical conductivity
    Patent number: 5484838
    Abstract: The invention is a molded thermoplastic article having a modified electrical conductivity and hence being particularly adapted for electrostatic painting. The article is composed of a composition comprising a polymer blend of at least two polymers and electrically conductive carbon black. The polymer blend comprises a crystalline polymer and an amorphous or semi-crystalline polymer, the crystalline polymer comprising at least about 35 weight percent of the blend.
    Type: Grant

  • Acrylic thermoplastic ionic conductor
    Patent number: 5337184
    Abstract: This invention is directed to a thermoplastic ionic conductor composition comprising a polymeric adduct having an acrylic backbone and polyether side chains, and an alkali metal salt. The polymeric adduct is made by reacting a particularly defined hydroxy-functional acrylic copolymer with polyether monoisocyanate. The composition is useful, e.g., in electrochromic devices as the electrolyte layer.
