摘　　要：用不同配比的聚碳酸酯(PC)和热塑性聚氨酯(TPU)以及增容剂丙烯腈-丁二烯-苯乙烯(ABS)的聚合物体系进行熔融共混制备共混物,用差示扫描量热仪、扫描电镜等测试观察共混物的形貌及结构,并测试了不同共混体系所制备共混物的力学性能。实验结果表明,加入少量TPU可以改善了PC的韧性,ABS增容剂作为第三组分的加入,能明显改善PC和TPU的相容性。The blends with a series of different proportions of PC/TPU/ABS were prepared by using melt blending.The morphology and compatibility of the blends were studied by differential scanning calorimetry and scanning electron microscopy.Moreover the mechanical properties of the blends were tested.The results show that adding TPU can improve the toughness of the PC.The compatibilizing can be improved by adding ABS compatibilizer.
