摘　　要：本文分别以氧化锌、氯化亚锡和辛酸亚锡为催化剂 ,采用两部法合成了聚d ,l-乳酸。用化学滴定法和粘度法测定了产物相对分子质量 ,并以红外光谱和DSC对产物进行了表征 ,结果表明所得为无定形聚乳酸 ,Tg为 53Poly( d,l -lactide) was synthesized with the ZnO,SnCl\-2 or Stannous Octoate as catalyst,respectively. The molecular weight was measured by chemical titration and viscosity. The resultant poly( d,l -lactide) was characterized by FTIR and DSC. The result shows the polymer is amorphous,and Tg is 53.3℃.
