Poly(aryl ether ether ketone) is found to be compatible with poly(aryl ether sulfone) at a blending temperature 310°C. There is a single glass transition temperature ( T g ) for various compositions of the blend. The relationship of T g with composition obeys Gordon‐Taylor's equation, where the adjustable parameter k is 0.43. Thermodynamic interaction parameter χ 12 is estimated to be ‐0.001 according to Nishi and Wang's melting point depression equation. When the processing temperature is above 350°C, phase separation takes place as shown by a double mechanical loss tangent relaxations in the range of 100–280°C.
