  • Process for the manufacture of an impact resistant thermoplastic resin
    Patent number: 5115031
    Abstract: A process for preparing a rubber modified thermoplastic resin, in which a latex in aqueous emulsion is prepared in the presence of a non-ionic surfactant; a vinyl monomer insoluble or substantially insoluble water is added, and the particles of the latex are transferred to the monomer to form an organic phase using a polymer or copolymer based on carboxylic acid units capable of forming an interpolymeric complex with the non-ionic surfactant; and a suspension or bulk polymerization of the organic phase is performed.
    Type: Grant
    Filed: April 6, 1990
    Date of Patent: May 19, 1992
    Assignee: Norsolor
    Inventors: Philippe Heim, Gerard Riess

  • Process for the manufacture of an impact-resistant thermoplastic resin
    Patent number: 4927867
    Abstract: A process for preparing a rubber modified thermoplastic resin, in which a latex in aqueous emulsion is prepared in the presence of an ionic surfactant; a vinyl monomer insoluble or substantially insoluble in water is added, and the particles of the latex are transferred to the monomer to form an organic phase using a transfer agent of opposite charge to the surfactant; and a polymerization of the organic phase is performed.
