聚乙烯改性的研究进展

Development in Modification of PE

本文综述了聚乙烯(PE)的改性方法,包括化学和物理改性。化学改性主要包括交联、接枝和共聚改性。物理改性则包括共混、填充和增强改性。介绍了填充改性时无机填料与聚合物基体之间存在的相容性问题。叙述了各种改性对PE共混体系性能的影响。最后,简介了国内外PE改性新技术的进展。

The modification methods are summarized in this article ,which include chemical and physical modifcations. The chemical modifications include cross-linking modification, grafting midification and coplymerization. And the physical modifications inckude blending, fillimg and strengrhening modification. The miscibility is elaborated durimg inorganic fillers and polymer in filling modification. The influence of fillers on PE blend is also discussed. At last, the article introduced the developments of PE modifications.
