Title (EN) POLYCARBONATE RESIN AND PRODUCTION METHOD THEREFOR
(FR) RÉSINE DE POLYCARBONATE ET SON PROCÉDÉ DE PRODUCTION
(JA) ポリカーボネート樹脂及びその製造方法
Abstract:
(EN) The purpose of the present invention is to provide a polycarbonate resin which has high fluidity and with which mold fouling such as mold deposits, etc., can be reduced. The polycarbonate resin according to the present invention has a terminal structure represented by general formula (1), and a viscosity-average molecular weight of 10,000-18,000, wherein the contained amount of low-molecular-weight carbonate compounds having a molecular weight of 1,000 or less contained in the polycarbonate resin is less than 1 mass%.
(FR) Le but de la présente invention consiste à préparer une résine de polycarbonate qui présente une fluidité élevée et grâce à laquelle l’encrassement du moule, par exemple des dépôts de moulage, etc., peut être réduit. La résine de polycarbonate selon la présente invention présente une structure terminale représentée par la formule générale (1), et un poids moléculaire moyen en viscosité de 10 000 à 18 000, la quantité contenue des composés carbonates de bas poids moléculaire présentant un poids moléculaire de 1 000 ou moins contenus dans la résine de polycarbonate étant inférieure à 1 % en masse.
(JA) 本発明は、流動性が高く、さらにモールドデポジットなどの金型汚れを低減することができるポリカーボネート樹脂を提供することを目的とする。本発明によれば、下記一般式(1)に示す末端構造を有し、かつ、粘度平均分子量が10,000~18,000であるポリカーボネート樹脂であって、 該ポリカーボネート樹脂中に含まれる、分子量が1,000以下の低分子量カーボネート化合物の量が1質量%未満である、ポリカーボネート樹脂が提供される。
