Title:
METHOD FOR PRODUCING ORGANIC-INORGANIC COMPOSITE HYDROGEL
Document Type and Number:
WIPO Patent Application WO/2017/164003
Kind Code:
A1
Abstract:
Provided is a method for producing an organic-inorganic composite hydrogel that comprises a polymer of a water-soluble organic monomer and a water-swellable clay mineral. The method comprises a step of polymerizing a water-soluble organic monomer in a dispersion containing the water-soluble organic monomer, a water-swellable clay mineral, a solvent and a polymerization initiator, wherein the molar ratio of the content of the polymerization initiator to the content of the water-soluble organic monomer in the dispersion (i.e., a (polymerization initiator)/(water-soluble organic monomer) ratio) is 0.005 or more.
Also provided is a method for producing an organic-inorganic composite hydrogel, wherein the solubility of the polymerization initiator in water is 5 g/100 mL or more.
