低聚(L-乳酸)的合成

Synthesis of L-lactic acid oligomer

本文采用熔融缩聚法制备了用于药物缓释制剂载体的低聚 (L -乳酸 ) ,研究了聚合工艺条件对聚合物产率及相对分子质量的影响 ,并采用IR、1H

L-lactic acid oligomer, which had been considered as a kind of materials used for drug delivery, was synthesized by melt polycondensation. The influence of the polymerizaton conditions on the yields and the molecular weight of L-lactic acid oligomer was studied. IR and 1 H-NMR methods were used to characterize the L-lactic acid oligomer.
