HYDROGEL AND METHOD FOR PRODUCING SAME

摘要

[Problem] To provide a hydrogel which is obtained by reacting an azide group and a cyclooctyne group in the absence of a catalyst, especially in the absence of a copper catalyst; in particular, to provide a hydrogel which can be used for a biocompatible material. [Solution] The above-mentioned problem can be solved by a hydrogel which has: (a) a first polymer moiety composed of hyaluronic acid, carboxymethyl dextran or the like; (b) a second polymer moiety composed of hyaluronic acid, carboxymethyl dextran or the like, said second polymer moiety being of a kind that is same as or different from the kind of the moiety (a) and is composed of a molecule different from the moiety (a); and (c) a triazole ring group or a derivative group thereof. The hydrogel has a structure wherein the first polymer moiety (a) and the second polymer moiety (b) are crosslinked with each other via the triazole ring group or a derivative group thereof (c).
