摘要/Abstract

摘要：

通过熔融共混法制备了聚对苯二甲酸乙二醇酯 (PET)/聚酰胺6 (PA6)/Surlyn与PET/均苯四甲酸酐 (PMDA)/Surlyn共混材料，研究了Surlyn对共混体系的形貌以及共混体系中PET流变性能与结晶性能的影响。并使用扫描电子显微镜观察了PET/PA6/Surlyn共混物的低温淬断断面，使用旋转流变仪与差示扫描量热仪研究共混物的流变性能与结晶性能。结果表明，Surlyn可以提高PET/PA6/Surlyn共混体系的熔体强度，促进共混体系中PET的结晶，使PET结晶温度提高10 ℃，过冷度与结晶半高宽显著下降，明显改善PET的流变性能与结晶性能，而对于PMDA扩链后的PET，Surlyn对其结晶性能的影响影响较小；Surlyn可以降低PA6分散相的粒径，提高PET与PA6两相之间的相容性。

Abstract:

Polyethylene terephthalate (PET)/polyamide 6 (PA6)/Surlyn composites and PET/ pyromellitic dianhydride (PMDA)/Surlyn composites were prepared by a melt blending method. The effects of Surlyn on morphology of composites, crystallization and rheological behavior of PET were investigated. The morphology of PET/PA6/Surlyn composites were observed by scanning electron microscope (SEM), and the result showed that Surlyn could decrease the diameter of PA6 dispersion phase particles and improve the compatibility of PET and PA6 phase. A rotational rheometer and a differential scanning calorimeter (DSC) was used to study the rheological and crystallization behavior of PET. And the result indicated that Surlyn could enhance the melt strength of PET/PA6/Surlyn composites significantly. Moreover, Surlyn could act as nucleating agent in PET/PA6/Surlyn composites to promote the crystallization temperature and accelerate the crystallization rate of PET considerably. And the rheological and crystallization properties of PET were improved. While Surlyn has no significant effects on the crystallization behavior of the PET that chain extended by PMDA.
