Abstract
There are provided compositions having superior impact resistance and improved solvent resistance comprising (a) an aromatic polycarbonate resin and (b) a minor amount of a selectively hydrogenated elastomeric block copolymer. The use of component (b) also 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 (a).
