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。
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.
