Abstract: front page image
(EN)Disclosed is a resin composition comprising a polylactic acid resin (A), a polycarbonate resin (B) and a methyl methacrylate copolymer (C). The ratio between the components (A) and (B) (i.e., a A/B ratio) is 40/60 to 80/20 by mass. The ratio between a melt flow rate of the component (A) (MFRA) to that of the component (B) (MFRB) (i.e., a MFRA/MFRB ratio) is less than 10 at 240˚C and under load of 21.2 N. The component (C) is a copolymer of methyl methacrylate and a (meth)acrylate ester and has a weight average molecular weight (Mw) of 500,000 or greater. The content of the component (C) is 0.1 to 20 parts by mass relative to 100 parts by mass of the total amount of the components (A) and (B).
(FR)L'invention porte sur une composition de résine comprenant une résine d'acide polylactique (A), une résine de polycarbonate (B) et un copolymère de méthacrylate de méthyle (C). Le rapport entre les composants (A) et (B) (à savoir le rapport A/B) est de 40/60 à 80/20 en masse. Le rapport de l'indice de fusion du composant (A) (MFRA) à celui du composant (B) (MFRB) (à savoir le rapport MFRA/MFRB) est inférieur à 10 à 240˚C et sous une charge de 21,2 N. Le composant (C) est un copolymère de méthacrylate de méthyle et d'un ester (méth)acrylate et a une masse moléculaire moyenne en poids (Mw) de 500.000 ou plus. La teneur du composant(C) est de 0,1 à 20 parties en masse par rapport à 100 parties en masse de la quantité totale des composants (A) et (B).
(JA) 樹脂組成物であって、ポリ乳酸樹脂(A)と、ポリカーボネート樹脂(B)と、メタクリル酸メチル系共重合体(C)とを含有する。(A)と(B)との質量比率(A/B)が、40/60~80/20である。240°C、21.2N荷重における(A)のメルトフローレート(MFR)と(B)のメルトフローレート(MFR)との比(MFR/MFR)が、10未満である。(C)は、メタクリル酸メチルと(メタ)アクリル酸エステルとの共重合体であり、その重量平均分子量(Mw)が500,000以上である。(C)の含有量は、(A)と(B)の合計100質量部に対して、0.1~20質量部である。
