(EN) HIGH FLOW, DUCTILE POLY(ALIPHATIC ESTER-CARBONATE) COMPOSITIONS
(FR) COMPOSITIONS DE POLY(ESTER-CARBONATE ALIPHATIQUE) DUCTILE, À ÉCOULEMENT ÉLEVÉ
Abstract
(EN)
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; an 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.
