Abstract: A thermoplastic composition, comprising, based on the total weight of the composition: 15 to 90 weight percent of a first poly(aliphatic ester-carbonate) having a first weight average molecular weight; 10 to 85 weight percent of a second poly(aliphatic ester-carbonate) having a second weight average molecular weight that is lower than the first weight average molecular weight; 0.01 to 0.5 weight percent of a mold release agent; 0.01 to 0.5 weight percent of a thermal stabilizer; 0.01 to 0.5 weight percent of a chain extender; San average melt volume flow rate of less than 40 cubic centimeters per 10 minutes when measured at 300° C. at a shear load of 1.2 kg, and an average melt volume flow rate of less than 40 cubic centimeters per 10 minutes when measured at 250° C. at a shear load of 5.0 kg.
