ABSTRACT
A very small amount of aryl amide derivative (TMB-5) was used for nucleating Poly(ethylene 2,6-naphathalate) (PEN) by melt blending. The crystalline temperature, crystallinity, and nucleation efficiency of the composites were increased as a result of the addition of TMB-5. The half-time of crystallization decreased upon the addition of TMB-5 and the work required in folding polymer chains were reduced simultaneously in the polymer mixtures. The crystal size of the PEN/TMB-5 blends became smaller due to the increase of nucleation sites. The TMB-5 had no effect on the PEN crystal type. TMB-5 slightly increased the impact strength of PEN.

通过芳基酰胺衍生物快速结晶聚(2,6-萘二甲酸乙二醇酯)
摘要
极少量的芳基酰胺衍生物(TMB-5)用于通过熔融共混来成核聚2,乙烯-萘二甲酸乙二醇酯(PEN)。由于添加了TMB-5,复合材料的结晶温度,结晶度和成核效率提高了。加入TMB-5后,结晶的半衰期减少了,同时在聚合物混合物中,折叠聚合物链所需的功也减少了。由于成核位点的增加,PEN / TMB-5共混物的晶体尺寸变小。TMB-5对PEN晶体类型没有影响。TMB-5稍微提高了PEN的冲击强度。
