| 摘 要： | 考察了聚乙二醇丁二酸酯(PESu)/酚醛树脂共混物的熔融和结晶行为。显示:酚醛树脂对PESu的结晶起异相成核作用,同时酚醛树脂的羟基对PESu分子链会产生干扰作用,降低其结晶能力,这两种作用的主次地位取决于共混物中酚醛树脂的含量。采用Avrami方程分析了该共混物的等温结晶动力学参数,并利用Arrhenius方程计算了共混体系的活化能变化。

| Abstract: | The crystallization and melting behavior of poly(ethylene succinate)(PESu)/phenolic blends were studied. The DSC results demonstrated that the phenolic played a the heterogeneous nucleation role to crystallizing of PESu, the hydroxy group of phenolic can interfere the molecule chain of PESu and reduce it's crystallizability. The isothermal crystallization parameters were deduced from Avriami equation. In addition, the activation energy of crystallization for PESu/phenolic blends was calculated by the Arrhenius relationship. |
