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 poly(carbonate-siloxane); 0.5 to 20 wt. % of compatibilizer polycarbonate component comprising a poly(carbonate-arylate ester); up to 15 wt. % of an ultraviolet light stabilizer; and 0 to 30 wt. % of TiO2; wherein a sample of the composition has a notched Izod impact energy of at least 200 J/m at 23&#xb0; C. measured in accordance to ASTM D256; and an at least 50% higher notched Izod impact energy value compared to the composition without the compatibilizer component measured in accordance to ASTM D256.

The disclosure relates to compositions exhibiting a UV resistance of &#x394;E ranging from more than 0 to less than or equal to 10 units after exposure to ultraviolet light for 300 hours, per ASTM D-4459 protocol. The compositions can include at least 15 wt % of a polyetherimide; at least 35 wt % of a polycarbonate; a polyetherimide siloxane; and optionally, at least one UV stabilizer. The disclosure also relates to methods of shaping such compositions and articles produced from such compositions.
