Posphazene-based polymer for tissue adhesion a method for preparing the same and use thereof

摘要

The present invention relates to a phosphazene-based polymer containing amino acid ester, polyethylene glycol, a group having a functional group for introducing a functional group at a terminal, and a catechol group bonded to a part or all of the functional groups directly or via a linker in a predetermined ratio. The present invention further relates to a production method thereof, and a composition for tissue adhesion containing the same as an active ingredient.
