摘　　要：综述了近年来聚乙二醇(PEG)共混改性体系的研究进展以及应用情况,对其发展前景进行了展望。PEG与高分子材料混容性好,是应用很广的共混改性材料。PEG共混材料大多采用溶液共混法、熔融共混法和化学交联法制备。采用PEG共混改性其他材料一方面可改善脆性,提高抗冲击性能,另一方面也可提高材料的亲水性和水溶性。The research progress and application situation of polyethylene glycol（PEG） blend modification systems in recent years are reviewed,and their development prospects are predicted.The PEG has good miscibility with other polymer materials,and is widely used as blend modification material.The PEG blend materials are prepared mostly by using solution blending method,melt blending method and chemical crosslinking method.By using PEG blend modifying other materials,the brittleness of the materials is improved,and their impact resistance increases,on the other hand,their hydrophilicity and solubility in water also increase.
