Abrégé
(EN) A polycarbonate resin composition or copolymer in which the main repeating unit includes a carbonate unit (a-1) having a fluorene ring in a side chain, a carbonate unit (a-2) represented by formula (a-2) (in the formula, W represents a C1-20 alkylene group or a C6-20 cycloalkylene group, R represents a C1-20 branched or linear alkyl group or an optionally substituted C6-20 cycloalkyl group, and u represents an integer of 0-3), and a carbonate unit (a-3) derived from 2,2-bis(4-hydroxyphenyl)propane, and 1) the molar ratio of carbonate unit (a-1) and carbonate unit (a-2) is 50/50-80/20, 2) the molar ratio of the total of carbonate unit (a-1) and carbonate unit (a-2), and carbonate unit (a-3) is 1:99-70:30. The polycarbonate resin composition or polymer is characterized by excellent heat resistance, transparency, and flex resistance and low phase difference.
(ZH) 一种聚碳酸酯树脂组合物或共聚物,其主要重复单元包含:侧链具有芴环的碳酸酯单元(a-1)、下述式(a-2)表示的碳酸酯单元(a-2)和由2,2-双(4-羟基苯基)丙烷衍生的碳酸酯单元(a-3),(式中,W表示碳原子数1~20的亚烷基或碳原子数6~20的亚环烷基,R表示碳原子数1~20的支链或直链的烷基、或者可具有取代基的碳原子数6~20的环烷基,u表示0~3的整数。)1)碳酸酯单元(a-1)与碳酸酯单元(a-2)的摩尔比为50/50~80/20,2)碳酸酯单元(a-1)和碳酸酯单元(a-2)的合计与碳酸酯单元(a-3)的摩尔比为1:99~70:30,该聚碳酸酯树脂组合物或共聚物的特征在于:耐热性、透明性、耐弯曲性优异,且相位差低。
