A commercial polycarbonate (PC)/acrylonitrile‐butadiene‐styrene (ABS) blend was reprocessed by injection molding to study the influence of reprocessing on the physical properties of the product. The modulus of elasticity and the yield stress are unaffected by reprocessing, whereas the break properties and the impact strength decrease. The effects observed are compared with those found in PC and ABS. The type of reactions taking place during reprocessing and the change of blend morphology are also discussed.
