目的研究尼龙6及其与线性低密度聚乙烯共混物的非晶样品的熔融行为. 方法采用DSC技术探讨了退火温度、退火时间、DSC扫描速率、以及连续多步退火等因素与冰水淬火样品中的尼龙6组分的熔融峰间的相互关系. 结果与结论上述因素对尼龙6组分的熔融行为有较大的影响,共混使尼龙6的结晶度和结晶完善度降低,随退火时间的延长结晶度提高. 与纯尼龙6相比,共混物中高温熔融峰的峰高明显降低.

Aim To investigate the melting behavior of polyamide-6 in polyamide-6/polyethy- lene blends crystallized from amorphous state. Methods DSC was used to test effects of annealing temperature, annealing time, DSC scan rate, and the step-wise annealing on the melting peaks of the ice-water quenched specimens. Results and Conclusion Varied melting peaks of PA6 component were obtained. The degree of perfection and the crystallization degree of PA6 crystals decreased in the blends, and the crystallization degree of PA6 increased with the increasing of the annealing time. The height of the upper melting peak of reference PA6 is higher than that in blends.
