Received: 4 March 2010; in revised form: 17 May 2010 / Accepted: 18 May 2010 / Published: 18 May 2010 Abstract: This work presents a new synthetic approach to aromatic and aliphatic polycarbonates by melt polycondensation of bisphenol A diacetates with alkylene- and arylenediphenyl dicarbonates. The diphenyl dicarbonates were prepared from phenyl chloroformate and the corresponding dihydroxy compounds. The process invol
