摘要：
Novel absorbable polymer blends are disclosed. The blends are useful for manufacturing medical devices having engineered degradation and breaking strength retention in vivo. The blends consist of a first absorbable polymeric component and a second absorbable polymeric component. The weight average molecular weight of the first polymeric component is higher than the weight average molecular weight of the second polymeric component. At least at least one of said components is at least partially end-capped by a carboxylic acid group. Further aspects are medical devices made therefrom.
