In the present paper, the time-temperature equivalence of fracture toughness of Poly (Phenylene Sulfide) (PPS) is discussed experimentally. The fracture toughness was measured by the three-point bending test under several temperatures and deflection rates. The master curve of the fracture toughness can be made according to time-temperature equivalent principle and the shift factor determined from the thermo-viscoelasticity. This master curve was confirmed by the results under rapidly variation of the deflection rate. The fracture toughness increases slightly as the temperature increases. It increases rapidly near the glass transition temperature and has maximum value with the transition from brittle to ductile fracture at the glass temperature. The fracture toughness at the rubbery region is more than one at the glassy region.
