摘　　要：通过熔融共混方法制备了聚对苯二甲酸乙二醇酯(PET)/沸石分子筛复合材料,考察了沸石分子筛在PET中的分散状态;从定性和定量两个方面研究了其结晶行为和结晶动力学;分析了其热稳定性。结果表明,沸石分子筛在PET中分散良好;沸石分子筛对PET具有很好的成核效果和加速PET结晶的作用,平均结晶速率是纯PET的2～3倍;热稳定性也比纯PET有较大幅度提高。PET/zeolite composite was prepared via melting blending. The thermal and crystallization behaviors of the composites were studied. It was found that zeolite was well dispersed in PET matrix, which increased the thermal stabilization of the composites and acted as a good nucleating agent. The crystallization rate of the composite containing 1 % zeolite was 2～3 times higher than that of neat PET.
