Abstract
(EN)
A thermoplastic resin composition of the present invention is characterized by comprising: a polycarbonate resin; a polycarbonate-polysiloxane copolymer resin wherein the average degree of polymerization of polysiloxane blocks is 80 to 100; a rubber-modified vinyl graft copolymer; a modified polyolefin comprising a repeating unit represented by chemical formula 1 and a repeating unit represented by chemical formula 2; talc; wollastonite; and an alkyl phosphate having 10-20 carbon atoms. The thermoplastic resin composition is desirable in terms of impact resistance, hardness, flowability, and the balance of such properties.
(FR)
Une composition de résine thermoplastique selon la présente invention est caractérisée en ce qu'elle comprend : une résine de polycarbonate ; une résine de copolymère de polycarbonate-polysiloxane, le degré moyen de polymérisation des blocs de polysiloxane étant de 80 à 100 ; un copolymère greffé vinylique modifié par un caoutchouc ; une polyoléfine modifiée comprenant un motif de répétition représenté par la formule chimique 1 et un motif de répétition représenté par la formule chimique 2 ; du talc ; de la wollastonite ; et un phosphate d'alkyle ayant de 10 à 20 atomes de carbone. La composition de résine thermoplastique est souhaitable en termes de résistance aux chocs, de dureté, d'aptitude à l'écoulement et d'équilibre de telles propriétés.
