PA6／PPO共混物的非等温结晶动力学

摘要

The non-isothermal crystallization behavior of PA6/PPO blends was studied with differential scanning calorimetry. The methods of Jeziorny and Mo were used to analyze the non-isothermal crystallization kinetics of the blends. Results demonstrated that the crystallization of PA6 could be accelerated by ppO,however,depressed by PPO-g-MAH, SEBS-g-MAH and SEBS. Both Jeziorny and Mo methods were suitable for the analysis of non-isothermal crystallization of PA6/PPO blends.%采用差示扫描量热法研究了聚酰胺6／聚苯醚（PA6／PPO）共混物的非等温结晶动力学。通过Jeziorny法、Mo法分别对非等温结晶过程进行处理。结果表明，PPO对PA6的结晶起促进作用，而马来酸酐接枝聚苯醚（PPO-g-MAH）、氢化聚苯乙烯-丁二烯-苯乙烯嵌段共聚物（SEBS）和SEBS-g-MAH对PA6的结晶起阻碍作用；随着冷却速率的增大-共混物的结晶度下降，半结晶时间减小；Jeziorny和Mo法都适合分析PPO／PA6的非等温结晶过程。
