The mechanical behavior and fracture toughness evaluation of polycarbonate (PC)/K resin (K) blends, with and without maleic anhydride grafted K resin (K-g-MAH) incorporated, have been studied. The effect of K-g-MAH on the mechanical performance of the PC/K blends was investigated. The results showed that both the tensile strength, elongation at break and impact strength of PC/K blends were improved considerably with incorporating K-g-MAH. This resulted from the melioration of compatibility between the PC and K resin phases. The essential work of fracture (EWF) method was employed to determine the fracture toughness of PC/K blends with and without K-g-MAH incorporated. The effect of composition on the EWF parameters of the blends was particularly investigated. The results showed that a significant improvement in wewe of PC/K blends appeared when the K-g-MAH was incorporated, but it hardly influenced the plastic deformation during the fracture process.
