摘　　要：利用广角 X 射线衍射(WAXD)、差示扫描量热仪(DSC)等手段研究了聚甲亚胺/MC 尼龙 6 分子复合材料的结晶行为.X-射线结果表明聚甲亚胺的加入基本上没有改变基体的晶型,仍以 晶型为主.在等温结晶动力学研究中发现聚甲亚胺加快了基体的结晶速率,尤其是当 PAM含量为 5%时,半结晶期明显减小.但是几个式样的 Avrami 指数变化不大.The crystallization behavior of polyazomethine/MC nylon 6 had been investigated by mean of WAXD、 DSC. The results of X-ray diffraction indicated that the addition of PAM did not alter the crystalline structure of the matrix, showing crystalline modification. In the experiment of isothermal crystallization, PAM enhanced the overall rate of nylon crystallization, particularly when the content of PAM amounted to five percent, whose half cry- stallization time reduced dramatically. However, the Avrami exponent was not significantly affected by the fibers and the Avrami exponent for all samples was about 2.
