TL;DR: An isosorbide type polycarbonate prepared by using as the diol component, which is a plant-originating diol, has a glass transition temperature higher than those of publicly known bisphenol-A types polycarbonates, is excellent in heat resistance; and a process for the production thereof is described in this paper.
Abstract: An isosorbide type polycarbonate prepared by using as the diol component isosorbide which is a plant-originating diol, which has a glass transition temperature higher than those of publicly known bisphenol-A type polycarbonates and isosorbide type polycarbonates and is excellent in heat resistance; and a process for the production thereof. The polycarbonate of the invention comprises structural units represented by formula (I) and has a glass transition temperature of 170oC or above as determined by differential calorimetry at a temperature rise rate of 10oC/min.
