Abstract: A melt-blend composition is formed from, based on the total weight of the melt-blend composition, 0 to 5 wt. % of an additive; and 95 to 100 wt. % of a polymer composition, wherein the polymer composition comprises, based on the total weight of the polymer composition, 5 to 95 wt. % of a first copolycarbonate consisting of bisphenol A carbonate units and first additional second copolycarbonate consisting of bisphenol A carbonate units and second additional carbonate units (phthalimidine carbonate units); and 0.001 to 0.1 wt. % of a transesterification catalyst, wherein the melt-blended composition has a haze of less than 15% and a transmission greater than 75%, each measured using the color space CIE1931 (Illuminant C and a 2° observer) at a 3.2 mm thickness.

Abstract: A poly(carbonate-ester) copolymer including carbonate units of the formula (I); and ester units of the formula (II) wherein: T is a C2-20 alkylene, a C6-20 cycloalkylene, or a C6-20 arylene; and R1 and J are each independently a bisphenol A divalent group, or a phthalimidine divalent group or a third divalent group of the formula (III), (IV), (V), (VI) or (VII) wherein Xa is a C6-12 polycyclic aryl, C3-18 mono- or polycycloalkylene, C3-18 mono- or polycycloalkylidene, -(Q1)x-G-(Q2)y- group wherein Q1 and Q2 are each independently a C1-3 alkylene, G is a C3-10 cycloalkylene, x is 0 or 1, and y is 1, provided that the at least one bisphenol A divalent group, at least one phthalimidine divalent group, and at least one third divalent group are present in the poly(carbonate-ester) copolymer.
