(57) [Abstract] [Purpose] To provide a hemostatic agent that has flexibility, adhesiveness, biocompatibility, low water absorption, and reduces the burden on patients. [Structure] D, L-lactide and polyethylene glycol having a number average molecular weight of 2000 to 6000 are used as raw materials, and the molar ratio of ethylene oxide unit and lactic acid unit obtained by polymerization is 52:48 30:70 and the number average molecular weight is Use a polymer in the range of 7800 to 15000 as a hemostatic agent. |
