POLYCARBONATE AND PROCESS FOR PRODUCING THE SAME

摘要

A polycarbonate comprising ether diol residues which can be produced from a carbohydrate of the formula: (1) and comprising diol residues of the formula: -O-(CmH2m)-O- (2) (wherein m is an integer of 2 to 12), wherein the ratio of ether diol residues to all the diol residues is in the range of 65 to 98 wt.%, the polycarbonate having a glass transition temperature of 90°C or higher.
