Surgical adhesives, comprising an NCO-terminated hydrophilic urethane prepolymer derived from an organic polyisocyanate and a polyol component comprising a polyester polyol derived from an electron-attracting group-containing dicarboxylic acid, such as 2-ketoglutaric acid, are capable of being easily hydrolyzed within a living body after a certain period of time. |
