摘　　要：介绍了环境降解塑料的降解机理及其分类,综述了光降解高分子材料、生物降解高分子材料的种类、制备方法、性能及其应用,指出了环境降解高分子材料存在的问题及发展方向。通过比较认为光降解高分子材料技术比较成熟,完全生物降解高分子材料发展前景看好,并对今后的发展提出了建议。In this paper the degradation mechanism and classification on environmental degradable polymer have been reviewed. The types, preparation methods, properties and applications of biodegradable polymeric materials and photodegradable polymeric materials were summarized. The problems and development direction was pointed out. It was thought that the techniques ofphotodegradable polymeric materials were relatively mature, the development prospect of fuUy biodegradable polymeric materials was bright. Furthermore, some suggestions about the future development of degradable polymeric materials were presented.
