The present invention relates to an aromatic polycarbonate composition which is stabilized by adding to an aromatic polycarbonate (containing substantially no chlorine atom) a very slight amount of at least one compound selected from a phosphorous acid diester and a phosphorous acid monoester and at least one compound selected from a phenolic antioxidant, a phosphorous acid triester and an organic phosphonite. This composition has the characteristics that molded products made therefrom are superior in hot-water resistance and steam resistance and recycling molding thereof causes substantially no coloration. Thus, this composition is high in industrial applicability.
La présente invention porte sur une composition du type polycarbonate aromatique stabilisée par l'addition à un polycarbonate aromatique ( essentiellement non chloré) une très petite quantité d'au moins un composé choisi parmi des diesters d'acide phosphoreux et un monoester d'acide phosphoreux, et au moins un composé choisi parmi des antioxydants phénoliques, un triester d'acide phosphoreux et un phosphonite organique. Les articles profilés obtenus à partir de cette composition ont des caractéristiques supérieures de résistance à l'eau chaude et à la vapeur; par conséquent, le moulage à l'étape du recyclage ne cause essentiellement pas de coloration. Cette composition est donc d'un grand intérêt industriel.
