摘　　要：研究了一种耐热聚乳酸,并对其进行了红外光谱、示差扫描量热分析、热重分析、X-射线衍射、热收缩及断裂强力等测试。同样条件下,这种耐热聚乳酸的热收缩率是普通聚乳酸的1/4,耐热性有了明显改善,强力略有提高。The heat resistant poly （lactic acid） was studied, the structure and properties were characterized by FTIR, DSC, TG, X-ray diffraction, heat shrinkage and breakage strength. Under same synthetic conditions, the heat shrink ratio of heat resistant poly（lactic acid） was about 1/4 of ordinary poly（lactic acid）, the heat resistance had been improved noticeably, and the strength had been improved slightly.

关 键 词：聚乳酸 耐热 热收缩 改性
