摘　　要：以对苯二甲酸、间苯二甲酸、新戊二醇及1,6-己二醇为原料进行四元共缩聚反应,得到聚酯型树脂.利用1H核磁共振谱测定聚酯中各组分含量,测试了聚酯的耐磨性,并用合成的聚酯与聚碳酸酯共混制备光导器件,利用SP-428型静电纸分析仪测试光导器件的光电性能.实验结果表明由聚酯和聚碳酸酯共混物制备的有机光导器件能有效地防止光疲劳现象.Random polyesters were prepared from terephthalic acid, isophthalic acid, neopentanediol and hexanediol, u-sing the technique of esterification under atmospheric pressure and subsequent polycondensation under vacuum. The composition of the polyesters was established by 1H-NMR spectroscopy, and the durability of the polymers was measured. The photoreceptors consisting of the blend of the copolyester and polycarbonate as binder were prepared, and their photo-electrical properties were studied. The results show that the resistance of the photoreceptors to light exposure is apparently improved by using the blend of the polyester and polycarbonate as binder.
