生物降解材料的研究进展

The development of biodegradable polymer materials

高分子材料在国民经济各部门已经得到普遍应用 ,但同时又带来严重的环境污染 ,文章主要介绍目前研究的几种可生物降解的高分子材料 (包括淀粉基降解材料、聚乳酸类降解材料、聚酸酐、可降解聚氨酯、PET/ PEG可降解材料 )的合成、性能等 .

Polymer material has been widely applicated in every department.But it also produces much pollution.This paper illustrates mainly synthesis methods,characters of several biodegradable materials(material based starch?P lactic acid?P acerbity anhydride?P ammonia ester?P treylene?P glycol).
