摘　　要：用差示扫描量热法研究了聚酰胺(PA)6的非等温结晶动力学,并分别用Ozawa法、Jeziorny法和莫志深方程法处理PA 6的非等温结晶行为。结果表明:Ozawa法和Jeziorny法均不能很好地描述PA 6非等温结晶过程;莫志深方程结合Avrami和Ozawa方程,可很好地描述PA 6非等温结晶过程;PA 6的结晶受温度的影响较大,一旦成核,结晶可在短时间内发展得比较完善。The authors studied non-isothermal crystallization kinetics of polyamide（PA） 6 by differential scanning calorimetry（DSC） and processed the non-isothermal crystallization data with Ozawa, Jeziorny and Mo equation. The results show that the Ozawa and Jezinorny method fail to appropriately describe the non-isothermal crystallization behavior of PA 6, whereas Mo equation combined with Avrami and Ozawa equation can do it ideally. The crystallization temperature played a crucial role in the crystallization of PA 6, and the crystallization can be completed perfectly in short time once the nucleation occurs.
