    • 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.
