    Abstract: A method for preparing a crosslinkable hyaluronic acid derivative is provided to ensure excellent bio compatibility, high viscoelasticity and superior stability to a hyaluronidase, and to be used as various bio compatibility materials of gel, insert for treating wrinkle, molding subsidiary material, insert for treating arthritis and drug carrier. A crosslinkable hyaluronic acid derivative of the chemical formula 1: [HA]-C(O)-NHNH-C(O)-R^1-C(O)-NHNH2 is prepared by reacting a hyaluronic acid or their salt or derivative, with a dihydrazide compound of an aliphatic dicarboxylic acid represented by the following chemical formula 2: H2N-NH-C(O)-R^1-C(O)-NHNH2, in the water-alcohol mixed solvent, in the presence of a carboxyl group activating agent. In the formulae, [HA] shows a hyaluronic acid except for a carboxyl group or their salt or derivative, and R^1 shows substituted or unsubstituted C3-C10 alkylene radical.

    Abstract: A multi-layer film comprising hyaluronic acid derivatives is provided to obtain a multi-layer film that is safe inside a human body and contains hyaluronic acid derivatives whose decomposition speed is controlled. A multi-layer film comprising hyaluronic acid derivatives includes a tissue adhesion layer and a porous support layer. The tissue adhesion layer contains hyaluronic acid derivative that is obtained by reacting polymer selected among polylactic acid, polyglycolic acid and lactic acid-glycolic acid polymer with the hyaluric acid. The porous support layer contains hyaluronic acid in the form of hydrogel and is disposed on the tissue adhesion layer. The polymer is coupled to the carboxyl group of the hyaluronic acid by interposing a linker therebetween.
