| 英文摘要 | By combining the Avrami and Ozawa equations, a new kinetic equation for describing the non-isothermal crystallization process of polymers was obtained. The comparison among the new method and other commonly used methods such as Jeziony and Ozawa methods was conducted with the syndiotactic I 2-polybutadiene ( st -1, 2 PB) as an example. The results suggested that the apparent Avrami exponent obtained by the Jeziony method can not predict the mechanism of non-isothermal crystallization of st-1, 2 PB. The Ozawa method is also limited in obtaining the reliable kinetic parameters because of the substantial curvatures in the Ozawa plots. However, the analysis based on the new method gives 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 new method,the mechanism of crystallization of st-1,2 PB can be predicated and the result is comparable with that obtained by the isothermal crystallization. The new method is an effective method for dealing with the kinetics of non-isothermal crystallization of many polymeric systems, such as PEAKs, polyamides, polyolefins, poly ( 3-alkylthiophenes) poly ( P-hydroxybutyrate) and some blending systems. |
