Abstract
(EN)
The purpose of the present invention is to provide a high temperature/humidity resistant polycarbonate resin without using bisphenol A as a raw material. The present invention relates to a polycarbonate resin comprising the repeating units of formulas (1), (2), and (3), wherein the content of the repeating unit of formula (3) is 5 mol% to 50 mol%, and the refractive index is 1.570 to 1.600. {In formula (1), R1 and R2 each represent a hydrogen atom or a C1-10 hydrocarbon group.} {In formula (3), n ranges from 0 to 8, and the R symbols are each selected from C1-3 alkyl groups.}
(FR)
La présente invention a pour but de fournir une résine de polycarbonate résistante à la température/à l'humidité élevée sans utiliser de bisphénol A comme matière première. Pour atteindre ce but, une résine de polycarbonate selon la présente invention comprend les motifs de répétition des formules (1), (2) et (3), la teneur du motif de répétition de la formule (3) étant de 5 % en moles à 50 % en moles, et l'indice de réfraction étant de 1,570 à 1,600. {Dans la formule (1), R1 et R2 représentent chacun un atome d'hydrogène ou un groupe hydrocarboné en C1-10.} {Dans la formule (3), n est compris entre 0 et 8, et les symboles R sont sélectionnés chacun parmi des groupes alkyle en C1-3.}
(JA)
本発明は、ビスフェノールAを原料として使用せず、かつ高温耐湿性が高いポリカーボネート樹脂を提供することを目的とする。 本発明は、式(1)、式(2)及び式(3)の繰返し単位を含み、下記(3)式の繰返し単位が5mol%以上50mol%以下であり、かつ屈折率が1.570~1.600である、ポリカーボネート樹脂に関する: {式(1)中、R及びRは、それぞれ水素原子又は炭素原子数1~10の炭化水素基を表す} {式(3)中、nは0~8の範囲であり、Rは、それぞれ炭素原子数1~3のアルキル基から選択される}。
