摘　　要：在用原位聚合方法制备聚甲亚胺/尼龙6复合材料的过程中,发现聚甲亚胺的加入对ε-己内酰胺本体聚合有显著的阻聚作用。本文采用改变醛/胺摩尔比的方法制备复合材料,借助红外光谱分析验证聚甲亚胺醛端基的阻聚机理;在此基础上,通过对复合材料的力学性能、尼龙6基体结晶度和聚甲亚胺分子量等的测定,进一步研究了聚甲亚胺端基对复合材料性能的影响,以期得到力学性能满足要求的复合材料。Polyazomethine (PAM) of polycondensation reaction of terephthalaldehyde (TPA) with 1,6-Hexanediamine (1,6-HAD) and its composites with ε-caprolactam, which was later polymerized, were prepared through an in-situ process. The effect of PAM chain ends on the polymerization of ε-caprolactam was observed obviously and the reasons were clarified by means of FT-IR spectra. Furthermore, the mechanical properties, crystallization of monomer casting nylon, the molecule weight of PAM were characterized with varying the molar ratios of aldehyde/amine. It is indicated that the PAM/MC nylon composites with expected properties could be readily synthesized from above experiments.
