| abstract | A poly(ester-carbonate) copolymer comprises carbonate units of the formula (I); and ester units of the formula (II) wherein: T is a C 2-20 alkylene, a C 6-20 cycloalkylene, or a C 6-20 arylene; and R 1 and J are each independently (a) a bisphenol A divalent group and (b) a C 16 or higher divalent group (b), wherein the C 16 or higher divalent group is present in an amount of 40 to 50 mol%; the ester units are present in an amount of 40 to 60 mol%; the poly(ester-carbonate) copolymer has a weight average molecular weight of 18,000 to 24,000 Daltons; and a sample of the composition has a glass transition temperature of 210 °C to 235 °C as determined by differential scanning calorimetry (DSC) as per ASTM D3418 with a 20 °C/min heating rate; and a melt viscosity of less than 1050 Pa- s at 644 sec-1 and 350°C, determined according to ISO 11443. |
