Patent

CA 2715204

The invention relates to impact resistant-modified polycarbonate compositions containing A) 50 to 99.4 parts by weight of aromatic polycarbonate and/or aromatic polyester carbonate, B) 0.5 to 20 parts by weight of rubber-modified graft polymer produced in an emulsion polymerization process, C) 0.1 to 30 parts by weight of a salt of a phosphinic acid, the parts by weight of each of components A, B, and C being relative to the total parts by weight of components A+B+C. Said polycarbonate compositions are characterized by an optimal combination of great thermostability, good resistance to chemicals, and good resistance to flames, especially in a glow-wire flammability test according to IEC 60695-2-12. The invention also relates to the use of said polycarbonate compositions for producing molded articles as well as said molded articles.

L'invention concerne des compositions polycarbonate à résilience modifiée contenant A) 50 à 99,4 % en poids (respectivement par rapport à la somme des parts en poids des composants A+B+C) de polycarbonate aromatique et/ou de polyestercarbonate aromatique, B) 0,5 à 20 % en poids (respectivement par rapport à la somme des parts en poids des composants A+B+C) de polymérisat greffé à modification caoutchouc fabriqué par polymérisation en émulsion, et C) 0,1 à 30 % en poids (respectivement par rapport à la somme des parts en poids des composants A+B+C) d'un sel d'un acide phosphinique, caractérisées par une combinaison optimale entre une résistance élevée au thermoformage, une bonne résistance aux agents chimiques, et un bon ignifugeage, notamment au cours du test au filement chauffant selon IEC 60695-2-12. L'invention concerne également l'utilisation des compositions polycarbonate pour la fabrication de corps moulés et les corps moulés eux-mêmes.
