Degradation rates of a copolymeric PLGA can be controlled by varying the constituent amount in the copolymer. In the present study we have made an attempt to utilize microwave irradiation to blend PLLA and PGA in different concentrations. FTIR, NMR and DSC measurements clearly show the blending and cross-linking between the constituents.
共聚物聚乳酸-羟基乙酸（PLGA）的降解速率可以通过改变共聚物中各成分的含量来控制。在本研究中，我们尝试利用微波辐射以不同浓度混合聚左旋乳酸（PLLA）和聚乙醇酸（PGA）。傅里叶变换红外光谱（FTIR）、核磁共振（NMR）和差示扫描量热法（DSC）测量清楚地显示了各成分之间的混合和交联。
