  A polyestercarbonate copolymer blend which exhibits a glass transition temperature lower than bisphenol-A carbonate homopolymer, shows good processability and fire-retardancy. The desired lower Tg and improved flow can be achieved by the polycondensation of a dihydric phenol and aliphatic dicarboxylic acid. The condensate is polymerized with a carbonate forming reagent.
