Notes:
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 (Tg) for various compositions of the blend. The relationship of Tg with composition obeys Gordon-Taylor's equation, where the adjustable parameter k is 0.43. Thermodynamic interaction parameter χ12 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.
