Abstract
A thermoplastic molding composition comprising a resinous blend of polycarbonate, polyester and an impact modifier and an additive amount of a siloxane compound containing a pendant oxirane group is disclosed. It was surprisingly and unexpectedly discovered that unlike the corresponding compositions which contain no siloxane compound, the inventive composition is capable of being dried at low temperatures prior to molding and still maintain high impact strength.
