Hydrogel product comprising polyion complex and method thereof

摘要

The present invention relates to a hydrogel product which comprises an anionic polymer having an average molecular weight of 100 kDa to 1,000 kDa and dextran substituted with an amine group, wherein the anionic polymer and dextran are grafted and a cationic functional group is complexed to the main chain of the anionic polymer, and a method for manufacturing the same. The hydrogel product is excellent in stability and adhesiveness in a living body while reducing water absorption of the hydrogel itself so as to have a wide range of applications.
