The thermal and mechanical properties of phenolphthalein polyethersulfone/poly(phenylene sulfide) (PES‐C/PPS) blends were studied using a differential scanning calorimeter, a dynamic mechanical analyzer, and mechanical characterization. The morphologies of fracture surfaces were observed by scanning electron microscopy. The blends are multiphase systems with strong interaction between the two phases. It is of interest that, although the strength and ductility of PPS are lower than those of PES‐C, the addition of PPS can improve markedly the impact strength of PES‐C without changing its higher strength. The PPS can also act as a flow aid for PES‐C. © 1995 John Wiley & Sons, Inc.
