Abstract

PURPOSE: To prepare a polymer having excellent solubility in water, by polymerizing an aqueous solution of a monomer mixture composed mainly of a water-soluble ethylenic unsaturated monomer, in the presence of a heavy metal salt and a reducing inorganic phosphorus compound using an azo compound as a polymerization initiator.
CONSTITUTION: The objective polymer is prepared by polymerizing (A) one or more water-soluble ethylenic unsaturated monomers selected from (meth)acrylamide, (meth)acrylic acid and aminoalkyl (meth)acrylate, or a monomer mixture containing the above monomers as main components, in an aqueous solution in the presence of (B) a heavy metal salt such as ferric sulfate and/or a reducing inorganic phosphorus compound such as metaphosphoric acid or its sodium salt using (C) 2,2'-azobis-N,N'-dimethyleneisobutylamidine hydrochloride etc. as a polymerization initiator.
