Abstract
PURPOSE: To obtain a dried polymer useful as a coagulant, etc. having a high coagulating property with a reduced amount of the residual monomer and a water- insoluble substance, by drying a hydrous acrylamide (co)polymer, etc. in the presence of an alkali metal salt of sulfurous acid, etc.
CONSTITUTION: Acrylamide or an acrylic monomer, e.g. sodium acrylate, or both are polymerized in an aqueous solution in the presence of ethylenediamine, etc. as a inhibitor for crosslinking and a redox system of potassium persulfate/tetramethylethylenediamine as a polymerization initiator, to give an acrylamide and/or acrylic acid polymer or copolymer. The resultant hydrous polymer is then dried in the presence of one or more hydrosulfites, sulfites and pyrosulfites (each alkali metal salt) to afford the aimed polymer.
