Copoly(carbonate-thiocarbonate)s were synthesized from bisphenol-A and mixtures of phosgene and thiophosgene under phase transfer conditions, using quaternary ammonium salts and dichloromethane as solvent at three temperatures. The copolymeric compositions were determined by i.r. spectroscopy and th
