Abstract

A melt blend composition, based on the total weight of the melt blend composition, formed from 0 to 5 wt.% of an additive and 95 to 100 wt.% of a polymer composition, wherein based on the total weight of the polymer composition, the The polymer composition comprises from 5 to 95 wt.% of a second bisphenol A carbonate unit consisting of bisphenol A carbonate units and a first other carbonate unit of formula (I), (II), (III), (IV) or (V) below A copolycarbonate; 95 to 5 wt.% of a second copolycarbonate consisting of bisphenol A carbonate units and a second other carbonate unit (benzopyrrolidone carbonate unit); 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 transmittance of greater than 75%, each measured using color space CIE1931 (illuminant C and 2° observer) at a thickness of 3.2 mm.

Description

technical field [0001] The present disclosure relates to compatibilized thermoplastic compositions, articles formed therefrom, and methods of making the same, in particular to compatibilized thermoplastic compositions having advantageous properties such as high heat resistance and good surface properties. Background technique [0002] Polycarbonates are useful in the manufacture of articles and components for a wide variety of applications ranging from automotive parts to appliances. Due to its widespread use, especially in the automotive, lighting and consumer electronics industries, it is desirable to provide polycarbonates with high heat capacity and good surface properties such as metallization capabilities. Furthermore, although metallized parts are generally opaque, haze in opaque parts can result in visible flow lines and microscopic roughness that reduce the reflective properties of the metalized part. Furthermore, once the part to be metallized is molded, the part ...
