摘要

Provided is a substance for preventing adhesion characterized by containing: (1) an A-B-A type or B-A-B type triblock copolymer in which the A segment contains a poly (&egr;-caprolactone- co- glycolic acid) and the B segment contains a polyethylene glycol; and (2) a polyethylene glycol and/or a methoxy-polyethylene glycol. The substance for preventing adhesion: exhibits a temperature-responsive sol-gel transition; is easier to prepare for use than existing substances; is easily applied to wounds with complex forms and structures; and exhibits stability and adhesion prevention effect over a desired period. Furthermore, said substance for preventing adhesion is easy to handle in case of laparoscopic surgery.
