A method and a calculation formula for calculating the non-isothermal kinetic parameters ［the apparent activation energy(E) and the apparent pre-exponential constant (A)］ of the exothermic crystallization/solidification reaction from peak temperatures of non-isothermal DSC curves under different constant cooling rate conditions were presented. The suitability conditions of calculating the values of E and A by the formula and Kissinger′s equation were compared, considering that Kissinger′s method is not suitable for calculating the values of E and A of exothermal crystallization/solidification reaction. Minus value of E obtained by Kissinger′s method for the titled reaction is unreasonable.
