摘要
采用间接开环聚合法合成了平均分子量为 444 ,848的聚乳酸 ,并对合成工艺作了优化。用IR对所得单体丙交酯和聚乳酸进行了结构分析 ,结果表明 ,丙交酯和聚乳酸的谱图中各官能团十分明显。
The of polylactic acid(PLA) was obtained by ring-opening polymerization and the synthesis conditions to get 444,848 molecular weight were optimized. The structures of lactide and PLA were identified by IR spectra.
