  • MEDICAL TREATMENT MATERIAL AND METHOD FOR PRODUCING SAME
    Publication number: 20240277891
    Abstract: A medical treatment material that forms a hydrogel upon contact with water contains a polymer (A) including a structural unit derived from an ethylenic unsaturated monomer (ma) which has a carboxyl group and a molecular weight of 115 or less, and a polymer (B) including a structural unit derived from an ethylenic unsaturated monomer (mb) which has a functional group E that is capable of forming a hydrogen bond with a carboxyl group, the polymer (B) not being the polymer (A). At least one of the polymer (A) and the polymer (B) includes a structural unit derived from an ethylenic unsaturated monomer (mc) differing from the ethylenic unsaturated monomers (ma) and (mb), and the monomer (mc) is not an ethylenic unsaturated monomer having a cross-linkable functional group.
