ABSTRACT:
There are provided compositions comprising (a) an aromatic polycarbonate resin; and (b) a precompounded polymer system comprising an olefinic resin and a selectively hydrogenated elastomeric block copolymer resin, alone or in further combination with an aromatic polycarbonate or styrene resin and, optionally a hydrogenated elastomeric block copolymer resin. The use of (a) and (b) together provides high impact strength and unexpectedly superior flowability in the molten state.
