  • Compositions based on flameproofed polyamide
    Patent number: 4247450
    Abstract: Polyamides flameproofed with a halogenated derivative and including cadmium oxide as an additive to improve the arcing resistance of the polyamide are disclosed. The polyamides are particularly useful in the manufacture of electrical components.
    Type: Grant
    Filed: May 7, 1979
    Date of Patent: January 27, 1981
    Assignee: Rhone-Poulenc Industries
    Inventors: Jacqueline Cerny, Robert Troncy
  • Compositions intended for the flameproofing of plastics
    Patent number: 4242240
    Abstract: Compositions based on red phosphorus and a phenolformaldehyde polycondensate.These compositions contain from 50 to 95% by weight of red phosphorus and from 5 to 50% by weight of a thermoplastic phenol-formaldehyde polycondensate of molecular weight between 120 and 1,500, wherein the molar ratio of formaldehyde to phenol is between 0.7 and 0.9.These compositions are intended for the flameproofing of plastics and do not evolve toxic products during use.
    Type: Grant
    Filed: March 23, 1978
    Date of Patent: December 30, 1980
    Assignee: Rhone-Poulenc Industries
    Inventors: Jacqueline Cerny, Gilbert Vivant
  • Flameproofed plastic compositions
    Patent number: 4208317
    Abstract: Compositions for the flameproofing of plastics, said compositions containing from 0.1% to 20% by weight, relative to the plastic, of red phosphorus in the form of particles having a mean diameter less than 200.mu., encapsulated in a polymer which does not have a melting point or softening point below 90.degree. C., and which has a molecular weight greater than 2,000.
    Type: Grant
    Filed: March 23, 1978
    Date of Patent: June 17, 1980
    Assignee: Rhone-Poulenc Industries
    Inventors: Jacqueline Cerny, Gilbert Vivant
  • Compositions intended for the flameproofing of plastics
    Patent number: 4188313
    Abstract: Compositions based on red phosphorus and epoxy resin for flame proofing plastics without the release of toxic products during use. The compositions consist of a pulverulent mixture containing from 50 to 95% by weight of red phosphorus and from 5 to 50% by weight of compounds having epoxy groups in their chain.
    Type: Grant
    Filed: May 28, 1976
