Title (EN) POLYCARBONATE RESIN COMPOSITION AND MOLDED ARTICLE THEREOF
(FR) COMPOSITION DE RÉSINE DE POLYCARBONATE, ET ARTICLE MOULÉ ASSOCIÉ
(JA) ポリカーボネート樹脂組成物、並びにその成形品
Abstract: front page image
(EN)Provided is a polycarbonate resin composition in which two types of polycarbonate resin having different molecular weights are combined with a polycarbonate oligomer and a fluidity enhancing agent obtained by polycondensing a monomer mixture comprising a bisphenol component, a dicarboxylic acid component, and, optionally, a biphenol component, such that the fluidity of a resin during molding can be improved without damaging characteristics such as transparency, mechanical strength, and heat resistance. Further provided is a molded article of the polycarbonate resin composition.
(FR)L’invention fournit une composition de résine de polycarbonate et un article moulé associé. Un agent améliorant la fluidité qui est constitué par polycondensation d’un mélange monomère à base d’un composant bisphénol, d’un composant acide dicarboxylique et de manière facultative d’un composant biphénol, dans des résines de polycarbonate de masse moléculaire de deux types différents, est mélangé avec un oligomère de polycarbonate. Ainsi, il est possible d’améliorer la fluidité lors d’un usinage par moulage d’une résine, sans perte de ses caractéristiques telles que la transparence, la résistance mécanique, la résistance à la chaleur, ou similaire.
(JA)異なる2種類の分子量のポリカーボネート樹脂に、ビスフェノール成分およびジカルボン酸成分、並びに任意でビフェノール成分からなるモノマー混合物を重縮合してなる流動性向上剤と、ポリカーボネートオリゴマーとを配合することで、透明性、機械強度、耐熱性等の特性を損なうことなく、樹脂の成形加工時の流動性を向上させることができる、ポリカーボネート樹脂組成物、並びにその成形品を提供する。
