Title (EN) POLYMER MIXTURE HAVING AROMATIC POLYCARBONATE, STYRENE-CONTAINING COPOLYMER AND/OR GRAFT POLYMER AND A FLAME-RETARDANT, ARTICLES FORMED THEREFROM
(FR) MELANGE POLYMERE COMPRENANT UN POLYCARBONATE AROMATIQUE, UN COPOLYMERE CONTENANT DU STYRENE ET/OU UN POLYMERE GREFFE ET UN RETARDATEUR DE COMBUSTION, ET ARTICLES COMPOSES DE CE MELANGE
Abstract: front page image
(EN)The invention relates to a polymer mixture which comprises an aromatic polycarbonate, a styrene-containing copolymer and/or a styrene-containing graft polymer and a flame-retardant. It has been found that the use of a certain type of flame-retardants, namely poly(aryl-arylene phosphates) or poly(aryl-arylene phosphonates) leads to a polymer mixture having improved properties. In particular a polymer mixture having a higher heat distortion temperature is obtained.
(FR)Mélange polymère comprenant un polycarbonate aromatique, un copolymère contenant du styrène et/ou un polymère greffe contenant du styrène et un retardateur de combustion. On a découvert que l'utilisation d'un certain type retardateurs, notamment de polyphosphates d'aryle-arylène ou de polyphosphonates d'aryle-arylène permet d'obtenir un mélange présentant de meilleures propriétés. On obtient notamment un mélage polymère présentant une température plus élevée de déformation thermique.
