Compatibilized compositions, articles formed therefrom, and methods of manufacture

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 copolyca...

Beschreibung
Zusammenfassung:	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 carbonate units of the formula (I), (II), (III), (IV) or (V); 95 to 5 wt.% of a 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.
