生物可吸收材料PDLLA的聚合条件研究

Study on conditions of polymerization of bioabsorbable PDLLA

通过乳酸脱水合成出高纯度的D ,L 丙交酯。以辛酸亚锡为引发剂 ,进行丙交酯开环聚合为聚乳酸 (PDLLA)的实验研究。讨论了D ,L

After dehydrating of lactic acid the high-purity D,L-lactide was prepared, this paper describes the experiment of ring-opening polymerization of D,L-lactide producing PDLLA which initiated with stannous octoate.Finally,discussing the factors which affect the ring-opening polymerization of D,L-lactide and polymerization conditions of PDLLA.
