Abstract
A composition useful in the fabrication of molded articles contains a blend of a polycarbonate, a high impact rubbery modifier such as a core-shell polymer and a catalyst quencher selected from a Group IB or IIB metal phosphate salts such as sodium dihydrogen phosphate wherein the hydroyltic stability is improved via the incorporation of an epoxy-functional polyester derived from the reaction of a polyfunctional epoxy compound and a carboxylic acid-functional polyester.
