Title:
HYDROGEL, METHOD FOR PRODUCING HYDROGEL, AND METHOD FOR PRODUCING MOLDED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2022/249904
Kind Code:
A1
Abstract:
Provided is a hydrogel which has an interpenetrating network structure or a semi-interpenetrating network structure, and which contains a first polymer having a three-dimensional network structure and a second polymer introduced into gaps of the three-dimensional network structure of the first polymer, wherein the first polymer contains, as monomeric unit, a cross-linkable monomer A1 having a bond with a bonding energy of 80 to 250 kJ/mol, the crosslinking degree of the second polymer is smaller than the crosslinking degree of the first polymer, and the content of the second polymer is 2-100 parts by mass relative to 1 part by mass of the first polymer.
