Abstract
PURPOSE:To efficiently obtain a high-molecular weight polycarbonate having excellent hydrolytic resistance stability in molding and heat resistance for a long period and hardly coloring in the absence of a catalyst, by reacting a biscarbonate of a bis(p-hydroxyphenyl)alkane. CONSTITUTION:A carbonate component selected from bis(p-hydroxyphenyl)alkane methylphenyl biscarbonate, bis(p-hydroxyphenyl)alkane dimethyl biscarbonate and bis(p-hydroxyphenyl)alkane diphenyl biscarbonate so as to provide 2:1-1:2, preferably 1:0.7-1:1.5 molar ratio of phenylcarbonate groups to methylcarbonate groups is reacted in the absence of a catalyst at 150-320 deg.C to afford the aimed polycarbonate in a short time. Since no solvent is used in polymerization, processes are simplified as compared with those in a conventional method.
