摘要
合成了半芳香族共聚尼龙PA10T/106,并通过核磁共振氢谱(1H NMR)确定了其结构。采用差示扫描量热法(DSC)对其非等温结晶及熔融行为进行了研究。Jeziorny法和Mo法被用来确定PA10T/106的非等温结晶动力学参数。研究发现,PA10T/106比PA10T熔点更低,有更宽的加工窗口。PA106的引入并没有改变PA10T的晶体生长方式,二者均为二维生长。在降温速率较小时,PA10T/106的结晶速率比PA10T略小,而当降温速率较大时,PA10T/106的结晶速率比PA10T大。
        The semi-aromatic copolymer nylon PA10 T/106 was synthesized and its structure was determined by1 H NMR analysis. The non-isothermal crystallization and melting behavior were studied by differential scanning calorimetry( DSC). Jeziorny method and Mo method were used to determine the nonisothermal crystallization kinetics parameters of PA10 T/106. The study shows that PA10 T/106 has lower melting point and wider processing window than PA10 T. The introduction of PA106 could not change the crystal growth mode of PA10 T. Both of them are two-dimensional growth. When the cooling rate is low,the crystallization rate of PA10 T/106 is slightly lower than PA10 T. When the cooling rate is high, the crystallization rate of PA10 T/106 is higher than PA10 T.
