Title:
COMPOSITION FOR FORMING HYDROGEL, HYDROGEL, AND METHOD FOR PRODUCING COMPOSITION FOR FORMING HYDROGEL
Document Type and Number:
WIPO Patent Application WO/2020/153382
Kind Code:
A1
Abstract:
Provided is a composition for forming a hydrogel that makes it possible to form a sterilized hydrogel having high mechanical strength. Also provided are a hydrogel in which the composition for forming a hydrogel is used and a method for producing the composition for forming a hydrogel. The composition for forming a hydrogel is characterized in that said composition for forming a hydrogel contains a vinyl alcohol polymer having an ethylenically unsaturated group and a polymerization degree of 450 or more, the introduction rate of the ethylenically unsaturated group is 0.01-10 mol% in all structural units constituting the vinyl alcohol polymer, and no microorganisms detectable by the sterility test method specified in the general test methods of the Japanese Pharmacopoeia are present.
