A polycarbonate process comprising contacting in the presence of a base, a .beta.-fluoroaliphatic carbonate, and a polyhydroxy compound selected from alcohols and/or phenols. The resulting polycarbonates are useful as polycarbonates per se, or useful in the preparation of high molecular weight polycarbonates which can be molded or formed into films, laminates or reinforced plastics by conventional techniques.
