  • Patent number: 6414060
    Abstract: Thermoplastic polycarbonate-ABS resin is rendered flame retardant by blending with the resin an O,O-diaryl-N-arylphosphoramidate, an arylene-N,N′-bis(O,O-diarylphosphoramidate) in which the nitrogen atoms are in the 1,3 or 1,4 positions on an arylene ring, or an N,N′-piperazinediylbis(O,O-diarylphosphoramidate). These flame retardants are halogen-free. They provide molded objects having high heat distortion temperatures, and high softening temperatures. Flame retardants of these types have been found to be thermally stable at temperatures of at least 260° C., and they did not discolor the polymer composition during exposure to molding temperatures.

  • Patent number: 6399684
    Abstract: The present invention relates to polyamide/polymer blends having a morphology enhancing reagent selected from a phosphorous containing compound such as a hypophosphite salt. Significant physical effects are seen in Tensile strength as well as Vicat softening points. The blends having polyamide and a polymer selected from, for example, a neutralized ethylene copolymer, and the phosphorous containing reagent are useful in producing molded parts and other fabricated parts requiring high strength and toughness. Molded parts produced from such blends also have high gloss, high abrasion/scratch resistance and good high temperature properties.
