摘要
研究了高分子量聚L-乳酸(PLLA)的制备技术,通过开环聚合法,使用单体L-丙交酯成功地合成了不同分子量的PLLA,采用红外光谱(FT-IR)、核磁共振氢谱(1H-NMR)、比旋光度等手段,对聚L-乳酸的结构性能进行表征。
In the paper, the preparation process of high molecular weight poly(L-lactic acid)(PLLA) was studied. PLLA with different molecular weight was synthesized via the ring-opening melting polymerization of L-lactide with stannous 2-ethyl hexanoate(Sn(Oct)2) as a catalyst, and the structures and properties of PLLA were carried out by means of FT-IR spectrum, 1 H-NMR spectrum, specific rotation, etc.
