摘要： A hydrophilic polymer is denatured with a gaseous denaturant or a powdery denaturant substance made from a liquid denaturant substance. The liquid denaturant substance is made into powders by, for example, a method of mixing the liquid denaturant substance with a water-insoluble compound, a method of cooling the liquid denaturant substance to or below its melting point to turn the same into a solid state. Consequently, the hydrophilic polymer can be denatured uniformly. In case that the hydrophilic polymer is denatured with a gaseous denaturant, the hydrophilic polymer and denaturant react with each other efficiently in a safe manner regardless of the size or shape of the hydrophilic polymer. In case that the hydrophilic polymer is denatured with the powdery denaturant substance, not only the liquid denaturant substance which is substantially in the solid state can be mixed with the hydrophilic polymer, but also the denaturation timing can be readily controlled.

摘要： The present invention provides a hydrophilicity-restoring agent for removing inorganic matter from a hydrophilic surface whose hydrophilicity has been reduced by the adhesion of the inorganic matter to thereby restore the hydrophilicity of the hydrophilic surface, and provides a method for restoring the hydrophilicity of a hydrophilic surface using the hydrophilicity-restoring agent. A gel of a hydrophilicity-restoring agent is prepared by mixing a thickener such as polyethylene glycol and xanthan gum with an aqueous solution in which a ligand such as citric acid to form a chelate complex is dissolved. The hydrophilicity of the hydrophilic surface is restored by applying the hydrophilicity-restoring agent to the hydrophilic surface with a reduced hydrophilicity and removing the hydrophilicity-restoring agent after an appropriate lapse of time.
