摘要
Bioabsorbable polymers employed as medical materials such as vascular stents and sutures have almost constant dynamic properties (tensile strength, etc.) and degradation speed due to absorption. In case of improving these dynamic properties, then these materials become fragile and the degradation speed is lowered. In case of elevating the degradation speed, then the dynamic properties are worsened and, as a result, there arises a problem that the purpose and site of using are restricted. Under these circumstances, a bioabsorbable polymer is copolymerized with a cyclic depsipeptide to give a copolymer having the ring-opening copolymerized depsipeptide. Thus, the dynamic properties and degradation speed can be controlled depending on the content of the depsipeptide.
