摘　　要：聚乙烯(PE)是目前应用生产薄膜最大的塑料品种之一,为了避免"白色污染",利用淀粉和无机填料改性聚乙烯制得可降解薄膜是目前最主要的两种手段。本文探讨了淀粉改性聚乙烯的工艺、机理和改性后薄膜的性能;同时讨论了不同无机填料改性聚乙烯的工艺、机理。Polyethylene is one of the largest plastic species using in films. At present, to avoid ＂white pollution＂, there are two main means to prepare the degradable polyethylene fihns by filling starch and inorganic filling. In this paper, the techniques and mechanism of starch modifying polyethylene, the properties of the films after modification were discussed. At the same time, the techniques and mechanism of inorganic fillings modifying polyethylene were illustrated.

关 键 词：聚乙烯 淀粉 无机填料 填充改性
