Abstract
Toughened poly(aryl ether sulfone)/poly(aryl ether ketone) blends. The present invention relates to polymer compositions including at least one poly(aryl ether sulfone) (PASS) polymer, at least one poly(aryletherketone) (PAEK) polymer, and at least one impact modifier (IM). The polymer composition may optionally include at least one aromatic polycarbonate (PC) and/or titanium dioxide (TiO2), The polymer composition is particularly suitable for use in mobile electronic devices.
