Porous hydrous gel molded product, method for producing the same, and use thereof

摘要

A porous water-containing gel molded product containing polyvinyl alcohol acetalized with dialdehyde, wherein the pore size of the freeze-dried product of the molded product is 0.1 to 50 μm provide. At this time, it is preferable that the porous hydrogel product further contains a water-soluble polysaccharide. It is also preferable that the degree of acetalization of polyvinyl alcohol is 1 to 50 mol%. It is also preferred that the porous water-containing gel molded product is particles, and the sphere equivalent diameter of the particles is 1 to 20 mm. Such a porous hydrogel molded product has high strength and good microbial habitability.
