Process for the production of acrylamide polymer dispersion |
| abstract |
This invention is related to a method of producing acrylic amide-based polymer dispersions which comprises polymerizing a water-soluble monomer composition containing an acrylic amide monomer in an aqueous solution of an inorganic salt in the presence of a homopolymer of vinyl-pyrrolidone and/or a copolymer of vinylpyrrolidone and another monomer, wherein the inorganic salt is present in an effective concentration for precipitation of the resulting polymer, in a case where said water-soluble monomer composition. containing an acrylic amide monomer is a mixture of acrylamide and sodium acrylate, the content of said sodium acrylate is not more than 40 mole percent based on the total amount of said acrylamide and said sodium acrylate. |
