摘　　要：利用聚乙二醇 (PEG)的端羟基与马来酸酐 (MAH)进行化学反应 ,制备了聚乙二醇双马来酸酯 (MPEG)。通过熔融共混的方法在PA6中混入质量分数为 2 %～ 10 %的MPEG ,制得PA6/MPEG共混物。MPEG的加入可起到增塑作用。随其加入量的增加 ,共混物的拉伸强度和洛氏硬度降低 ,缺口冲击强度增大 。Polyethylene glycol dimaleate (MPEG) was prepared by the reaction between the hydroxyl end group of PEG and MAH. 2%～10% mass fraction of MPEG was blended into PA6 by means of melt blending to get PA6/MPEG blend. The addition of MPEG had the effect of plasticization.The tensile strength and the Rockwell hardness of the blend decreased while the notched impact strength increased with the increase of MPEG, and the hydrophilicity of the blend increased obviously.
