AB - A two‐step, catalytic, anhydrous solution process was developed for the preparation of the polycarbonate of 2,2‐bis(p‐hydroxyphenyl)propane (bisphenol‐A). It involves the preparation of the dichloroformate of bisphenol‐A followed by its condensation with bisphenol‐A in the presence of magnesium metal. Attempts were also made to develop a one‐step, catalytic solution process. The reaction of bisphenol‐A with phosgene, in the presence of aluminum chloride, a very powerful catalyst, led to polymers with reduced viscosities as high as 0.35. Higher viscosities were not obtained due to the lack of a suitable, nonreactive solvent.
