Abstract

A polymer blend including 5 to 95 weight percent of a poly(ester-carbonate-carbonate) comprising 40 to 95 mole percent of ester units comprising low heat bisphenol groups and high heat bisphenol groups, wherein the ester units comprise 20 to 80 mole percent of the low heat bisphenol groups and 20 to 80 mole percent of the high heat bisphenol groups, based on the total moles of ester units in the poly(ester-carbonate-carbonate), and 5 to 60 mole percent of carbonate units comprising the low heat bisphenol groups and the high heat bisphenol groups, wherein the carbonate units comprise 20 to 80 mole percent of the low heat bisphenol groups and 20 to 80 mole percent of the high heat bisphenol groups, based on the total moles of carbonate units in the poly(ester-carbonate-carbonate); and 5 to 95 weight percent of a poly(etherimide), wherein the weight percent of each polymer is based on the total weight of the polymers in the blend, and a molded 0.125-inch thick ASTM tensile bar comprising the polymer blend has a haze value of less than 25% as determined according to ASTM D1003 using the color space CIE1931 (Illuminant C and a 2° observer).
