摘要: 采用变温红外光谱、差小扫描量热仪研究了聚醚胺6(PA6)/ N, N一乙撑双四澳邻笨二甲醚业胺(EPT)体系的结晶性能,通过动态力学热分析仪考察了该体系的储能模量与损耗因子。实验结果表明,EPT的加入有利于PA6/EPT体系的α晶型形成,使结晶温度提高,并形成两种强羽不同的氛键作用,体系表现出一个较低的α1松弛峰和一个较高的α2松弛峰。

Abstract: The crystalline properties of polyamide 6(PA6)/N一N’一ethylene一his(tctrabromoph-thalimidc)(FPT) blends were investigated by Fouricr transform infrared (FTIR) and differential scannine calorimctry (DSC),stora}c modules and loss factors were studied with dynamic mechanical thermal analysis. The results show that EPT's accession is advantageous to form a crystal and crystallization at a higher temperature in PA6 and FPT blends. Forming two different hydrogen bonding,the blends exhibit a lower a, relaxation transition peak and a higher α2 relaxation transition peak.
