CATALYST FOR PRODUCING POLYCARBONATE AND METHOD FOR PRODUCING THE POLYCARBONATE

摘要

PROBLEM TO BE SOLVED: To provide a method for stably and easily producing a high-quality polycarbonate in high yield without using a toxic chlorine gas or phosgene. SOLUTION: The catalyst for producing the polycarbonate is provided, comprising (a) a palladium complex of the general formula(I) and (b) a compound having redox catalyzing ability. The method for producing the polycarbonate comprises carrying out a reaction of an aromatic hydroxy compound or aliphatic dihydroxy compound with carbon dioxide and oxygen in the presence of the catalyst.
