  • Publication number: 20100010172
    Abstract: The present invention relates to a toughened transparent thermoplastic composite of a transparent thermoplastic and a block copolymer having a block of a random copolymer and an elastomeric block. One preferred embodiment is a polycarbonate that is modified with a block copolymer having a methyl methacrylate (MMA) and naphthyl methacrylate or a substituted naphthyl methacrylate block and an elastomeric block. This block copolymer has excellent miscibility with polycarbonate resin, even at elevated temperature, producing transparent polycarbonate blends. The blend can provide a toughened strength polycarbonate while maintaining its excellent optical properties.

  • Patent number: 6833414
    Abstract: A cross-linkable fluoropolymer dispersion is described and involves a polymer product of at least one polymerizable acrylic and/or vinyl containing monomer and at least one hydrolytically stable silane containing monomer which are in the presence of an aqueous dispersion of at least one fluoropolymer. The present invention further relates to cross-linkable fluoropolymer blends wherein at least one polymer contains acrylic units, vinyl units, or both and at least one hydrolytically stable silane or silane containing group in the presence of at least one thermoplastic fluoropolymer. The silane or silane containing group can alternatively be present in the thermoplastic fluoropolymer. Methods of making the cross-linkable fluoropolymers are also described as well as products containing the cross-linkable fluoropolymer dispersions such as paints and coatings.
