Abstract: Described herein are polyarylate molding compositions having improved notched izod impact values after molding, which composition comprises a blend of a polyarylate, a polyester, and an impact modifier which is a graft copolymer of a vinyl aromatic, an acrylate, an unsaturated nitrile, or mixtures thereof, grafted onto an unsaturated elastomeric backbone and having a tensile modulus of less than about 100,000 psi. Also, decabromodiphenyl oxide may be included in said composition.
