Process for production of highly water-absorbent resin |
摘要 |
In a process for producing a highly water-absorbent resin comprising subjecting a mixture of (meth)acrylic acid with a water-soluble salt thereof as a monomer to reversed phase suspension polymerization in a hydrophobic solvent in the presence of a dispersing agent, improvements that at least a portion of said monomer is fed sequentially with the progress of polymerization reaction and at least a portion of said dispersing agent is fed sequentially with the progress of polymerization. The resulting resin is useful as a highly water-soluble resin component of sanitary products, or as a humectant/desiccant, a rheology modifier and so on.
