摘要： A polycarbonate resin reduced in the release of environmental hormones which comprises structural units represented by general formula (A) and structural units represented by general formula (B), the structural units represented by general formula (A) accounting for 5 to 90 mol % of all the structural units, and which has an intrinsic viscosity of 0.30 to 0.60 dl/g. The polycarbonate resin is produced through the copolymerization of a bispenol whose ability to link to estrogen acceptors is low with an aliphatic dihydroxy compound. The resin hence has the basic properties inherent in polycarbonates, i.e. mechanical strength and heat resistance, and is reduced in the release of environmental hormones.
摘要翻译：通式（A）表示的结构单元和由通式（B）表示的结构单元的环境激素释放减少的聚碳酸酯树脂，由通式（A）表示的结构单元占5〜90摩尔％所有结构单元，其特性粘度为0.30〜0.60dl / g。聚碳酸酯树脂通过双酚的共聚制备，其与雌激素受体连接的能力低于脂族二羟基化合物。因此，树脂具有聚碳酸酯固有的基本特性，即机械强度和耐热性，并且减少了环境激素的释放。
