【摘要】 随着人们对废弃高分子材料造成环境污染的日益认识,对生物可降解材料的研究得到了重视和发展。本文对高分子材料的降解机理和目前在聚酯纤维方面已取得的进展进行了讨论。着重介绍了目前研究有所发展的聚乳酸(PLA)、聚(β-羟基丁酸酯)(PHB)和聚丁二酸酯类等近几年的工作。更多还原

【Abstract】 Waste macromolecular materials have polluted the environment. Lots of researches on biodegradable material have been done to solve the problem. In this paper, the mechanism of biodegradation is discussed. And the development of biodegradable polyester fibers, such as PLA fiber,PHB fiber, etc. is introduced. (60 Ref.)更多还原
