PURPOSE : A manufacturing method of polymer coagulant is provided to manufacture an excellent coagulant and dehydration effect polymer coagulant with high biodegrability and environmental friendly.CONSTITUTION : A manufacturing method of polymer coagulant comprises a step of manufacturing mixed solution of starch, (meth)acrylamide, and ionic monomer, a step of manufacturing a reaction solution by adding rare earth resource catalysts, and a step of manufacturing polymer by radiating the gamma ray to the reacting solution. From the manufacturing step, 5-95 parts by weight of starch according to the 100 parts by weight of (meth)acrylamide, and 5-100 parts by weight of ionic monomer to the mixture.COPYRIGHT KIPO 2013
