MANUFACTURING METHOD FOR GRAFT POLYMERIZATION SUBSTANCE, AND HEAVY METAL SCAVENGER

摘要

<P>PROBLEM TO BE SOLVED: To provide a graft polymerization substance as a stable water suspension with flowability by graft-polymerizing a reactive monomer with a polysaccharide and/or its derivative. Ž<P>SOLUTION: In the method of manufacturing the graft polymerization substance by graft-polymerizing the reactive monomer with the substance comprising the polysaccharide and/or its derivative, the suspension in which the polysaccharide and/or the derivative is suspended in an aqueous medium containing a thickener is irradiated with radiation in the presence of the reactive monomer.
