摘　　要：通过“一锅法”进行聚合反应,分别制得半芳香型聚酰胺聚对苯二甲酰癸二胺(PA10T)及其共聚物聚对苯二甲酰癸二胺/聚十二碳二酰癸二胺(PA10T/1012),并采用差示扫描量热法(DSC)对PA10T和PA10T/1012的非等温结晶行为进行了详细研究和对比。结果表明,PA10T和PA10T/1012均呈现单结晶峰,且峰宽随降温速率的增加而增大;当降温速率相同时,PA10T/1012的结晶温度比PA10T低。对其非等温结晶参数进行分析,结果表明,PA10T/1012的结晶速率明显低于PA10T。通过Mo法对两种树脂的非等温结晶行为进行了分析,结果表明,为使PA10T/1012在单位时间内获得与PA10T相同的相对结晶度,需提高PA10T/1012的降温速率。利用Kissinger法和Takhor法分别计算得到PA10T和PA10T/1012的非等温结晶活化能,两种方法的计算结果相近。Semi-aromatic polyamides poly(decamethylene terephthalamide)(PA10T)and the corresponding copolymer poly(decamethylene terephthalamide)/poiy(decamethylene dodecanediamide)(PA10T/1012)were respectively prepared by‘one-pot’synthesis method.The non-isothermal crystallization kinetics of PA10T and PA10T/1012 were studied and compared by differ-ential scanning calorimetry(DSC)in details.Results show that both PA10T and PA10T/1012 appear single crystallization peak,and the peak width increases with a raise of the cooling rate.The crystallization temperature of PA10T/1012 is lower than that of PA10T at a same cooling rate.Analysis of the non-isothermal crystallization data shows that the crystallization rate of PA10T/1012 is much lower than that of PA10T.The non-isothermal crystallization kinetics of both resins were analyzed by the Mo method,which shows that a higher cooling rate for PA10T/1012 is required to obtain a same relative crystallinity with PA10T in a specific time.The val-ues of non-isothermal crystallization activation energy for PA10T and PA10T/1012 were respectively calculated by the Kissinger method and Takhor method.These two methods are found to have close results.
