Zusammenfassung:There are provided compositions comprising (a) a selectively hydrogenated elastomeric block copolymer, (b) a polycarbonate and (c) an amorphous polyester. The use of the combination of (a) and (c) provides remarkable improvements in the melt flow characteristics, in resistance to brittle failure, and in the resistance to environmental stress crazing and cracking of the polycarbonate resin component (b).
