PROBLEM TO BE SOLVED: To provide a method for obtaining a gel composition in which problems such as phase separation do not arise by gelling a gelation reaction system containing an aqueous solvent homogeneously and directly by a comparatively simple process.SOLUTION: The method of manufacturing a gel composition is characterized as follows. The crosslinking reaction of a water-soluble polymer which consists of a polyethylene imine based polymer is carried out under a uniform gelling condition in an aqueous solvent, and thereby a reaction system containing the aqueous solvent is directly made a gel-like substance which consists of a homogeneous phase substantially. |
