中文摘要：

用差示扫描量热仪（DSC）研究PBSA和PBSA／膨胀型石墨／水滑石复合材料的非等温结晶过程，结果表明：膨胀型石墨／水滑石可以提高PBSA的结晶温度，并可以将其非等温结晶温度提高15～22℃。通过Jeziornyz用于非等温结晶峰修正的Avrami方程拟舍得到PBSA和PBSA／膨胀型石墨／水滑石复合材料的n值分别为4．3～4．9和4．2～6．3，但是Ozawa方法在实验中并不能得到理想的处理结果。通过莫志深法进一步处理此非等温结晶过程，可以计算得到Ozawa指数m为3．0和2．7，表明膨胀型石墨／水滑石在PBSA体系中起到了异相成核的作用。

英文摘要：

The nonisothermal crystallization kinetics of neat PBSA and PBSA/expansion graphite/houphite composite were investigated by using differential scanning calorimetry （DSC）,which represented that expansion graphite/houphite could increase the crystallization temperature by 15 -22 ℃. According to Avrami equation modified by Jeziorny, the nonisothermal crystallization process of neat PBSA and the aforementioned composite were analyzed,indicating that the Avrami exponent n of which were 4.3 - 4.9 and 4.2 - 6.3. Ozawa method was failed to represented the experiment, but Mo＇ s method successfully obtained the Ozawa exponent m of neat PBSA and the composite were 3.0 and 2.7, which stated expansion graphite and houphite exhibited excellent nucleation activity for the crystallization of PBSA.
