| 英文摘要 | According to Mo et al. research oil non-isothermal crystallization process of polymers, an equation for describing the non-isothermal crystallization kinetics of polymer was obtained by combining the Avrami equation and Ozawa equation. The Avrami equation modified by Jeziorny could described only the primary stage of non-isothermal crystallization kinetics of polymers. The apparent Avrami exponent obtained by the Jeziorny method can not predict the mechanism of non-isothermal crystallization of polymers. The Ozawa equation is also limited for the non-isothermal crystallization process of many polymers, in obtaining life reliable kinetic parameters because of the substantial curvatures In the Ozawa plots. The changing slopes indicate that Ozawa exponent m is not constant Willi temperature during the primary crystallization process. The substantial curvature makes it impossible to determine the cooling or heating function (K(T)) over the entire crystallization process. However,the analysis based off the new Method could give a series of straight lines. According to the relationship among the new parameter a, the apparent Avrami exponent n, and the Ozawa exponent m in the flew method, the mechanism of crystallization of the polymer can be predicated and the result is comparable with that obtained by life isothermal crystallization The new method is an effective method for dealing with the kinetics of non-isothermal crystallization of many polymer systems such as PAEKs, polyamides, poly(ethylene oxide), polyolefines, poly (3-alkylthiophenes), poly(beta-hydroxybutyrate) and many blending systems. |
