    摘要: Provided is a hydrogel-forming composition capable of forming a sterilized hydrogel having a high mechanical strength. Also provided are a hydrogel using the hydrogel-forming composition, and a method for producing the hydrogel-forming composition. The hydrogel-forming composition contains a vinyl alcohol polymer having an ethylenically unsaturated group and having a polymerization degree of 450 or more, in which the ethylenically unsaturated group introduction ratio is 0.01 to 10 mol% in all the structural units constituting the vinyl alcohol polymer, and in which no microorganisms detectable by the sterility test method (direct method) specified in the general test methods of the Japanese Pharmacopoeia are present.
