  • Thermoplastic polycarbonate compositions with improved mechanical properties, articles made therefrom and method of manufacture
    Publication number: 20060287422
    Abstract: A thermoplastic composition comprising a polycarbonate resin, a mineral filler and an acid or an acid salt, and optionally an aromatic vinyl copolymer and/ or an impact modifier, has been found to exhibit improved characteristics and less degradation than filled thermoplastic compositions without the acid or acid salt. In some embodiments the composition exhibits improved impact and ductility, as well as molecular weight retention. An article may be formed by molding, extruding, shaping or forming such a composition to form the article.

  • Translucent thermoplastic composition, method for making the composition and articles molded there from
    Publication number: 20060014919
    Abstract: A thermoplastic composition comprising a matrix of a polycarbonate polymer in which are embedded polysiloxane domains with an average domain size between 20 and 45 nanometers. Said compositions can be obtained by combining a first polycarbonate/poly(diorganosiloxane) copolymer; with a second polycarbonate/poly(diorganosiloxane) copolymer. A range of translucencies are obtainable by varying the relative amounts of the two copolymers without substantial loss in impact properties.

  • Method for the pyrolysis of a pyrolysable mass
    Publication number: 20050167259
    Abstract: A method of pyrolysis wherein pyrolysable particles mixed with heated carrier particles are treated at an elevated temperature yielding a flammable product. According to the invention, use is made for mixing a rotating, vibrating or shaking element or by mixing at a volume density of less than 40%, and mixing occurs to a specified minimum degree after the mixture is deposited and is pyrolysed in the reactor after depositing.
