又名聚丙交酯-乙交酯 英文名Poly(lactide-co-glycolide) (PLGA) 分子结构式 外观性状：粉体、块状、颗粒和纤维 材料特点：PLGA是PLA和PGA的共聚物，是脂肪族聚酯中最为常用的一种共聚物，具有生物相容性和生物降解性。LA和GA的比例一般为90:10，80:20，70:30等，分子量5-15万可调，也可根据客户需求定制。由于PLA和PGA的降解速率不同，通过调节两者共聚比例和分子量，能够获得不同降解时间、不同力学性能的可降解高分子材料，适用于组织工程支架、器官支架、软硬组织修复、美容填充、药物载体等。 保存条件：长期保存于-20 oC冷冻，真空包装条件下。短期可保存于真空干燥器。
