A new kinetic equation of non-isothermal crystallization was derived by combining Av-rami and Ozawa equations. More crystallizatic informations can be obtained from the new equation. The kinetics of non-isothermal crystallization of poly(ethylene oxide) (PEO)/poly (hydroxy ether) of bisphenol A (PBHE) blends have been investigated by using differential scanning calorimetry
and the experimental results analysed showed agreements with the new kinetic equation.
