Abstract

A thermoplastic composition comprises, based on the total weight of the thermoplastic composition, 10 to 45 wt. % of a poly(etherimide); 35 to 90 wt. % of a polycarbonate component comprising a polycarbonate homopolymer, a poly(carbonate-siloxane), or a combination thereof; 0.5 to 20 wt. % of a compatibilizer polycarbonate component comprising a poly(carbonate-arylate ester), a phthalimidine copolycarbonate, or a combination thereof; up to 5 wt. % of an ultraviolet light stabilizer; and 0 to 20 wt. % of TiO2,wherein a sample of the composition has a 50% higher notched Izod impact energy value compared to the composition without the compatibilizer component.
