Abstract
A monocarbonate transesterification process comprising contacting in the presence of a base, a beta-fluoroaliphatic carbonate and a compound selected from the class consisting of monohydroxy aliphatic alcohols, phenols and ortho-positioned dihydroxy aromatic compounds. The resulting monocarbonates are useful as monocarbonates, per se, or useful in the preparation of polycarbonates which can be molded or formed into films, laminates or reinforced plastics by conventional techniques.
