| 摘 要： | 考察了聚碳酸酯与聚乙烯（ＰＣ／ＰＥ）及聚碳酸酯与马来酸酐接枝聚乙烯（ＰＣ／ＰＥ－ｇ－ＭＡＨ）共混体系的力学性能，研究了共混体系的相容性，研究表明，ＰＥ的加入有效地提高了ＰＣ的抗冲击性能，而ＰＣ／ＰＥ－ｇ－ＭＡＨ体系的力学性能及混溶性优于ＰＣ／ＰＥ体系。红外光谱表明，接枝ＰＥ与ＰＣ共混时，发生酯交换反应，冲击断口及样条截面的扫描电镜发现，ＰＣ／ＰＥ－ｇ－ＭＡＨ的相态分布均匀，两相之间存在一定的相互作

| Abstract: | The PE g MAH samples were prepared by grafting reaction of MAH onto polyethylene. The mechanical properties and compatibility of PC/PE and PC/PE g MAH blends had been studied. The impact strength of the two blend systems is higher than that of PC. The mechanical properties and the miscibility of PC/PE g MAH system are better than PC/PE system. IR spectra revealed that there is an ester exchange reaction happened in the PE g MAH blend system. By SEM and DSC, we studied the compatibility of the two systems. The compatibility of the two blend phase of PC/PE g MAH system is better than that of PC/PE system. |
