Abstract
(EN)
The present invention pertains to a thermoplastic resin composition obtained by blending a polycarbonate resin (I), a specific graft copolymer (II), a vinyl copolymer (III), an inorganic filler (IV), and a phosphate ester compound (V), wherein the weight average molecular weight of the vinyl copolymer (III) is 110,000 or less, the ratio of the melt flow rates of the vinyl copolymer (III) and the polycarbonate resin (I) is 7-12, and the blended amount of the phosphate ester compound (V) is 1-10 parts by weight with respect to 100 parts by weight of the total of (I)-(IV).
(FR)
La présente invention concerne une composition de résine thermoplastique obtenue par mélange d'une résine polycarbonate (I), d'un copolymère greffé spécifique (II), d'un copolymère vinylique (III), d'une charge inorganique (IV) et d'un composé ester de phosphate (V), le poids moléculaire moyen en poids du copolymère vinylique (III) étant de 110 000 ou moins, le rapport des débits de fusion du copolymère vinylique (III) et de la résine polycarbonate (I) étant de 7 à 12 et la quantité mélangée du composé ester de phosphate (V) étant de 1 à 10 parties en poids par rapport à 100 parties en poids du total de (I) à (IV).
(JA)
