The present invention provides a water-in-oil monomer dispersion comprising (a) water, an oily substance, a water-in-oil emulsifier, a polymer coagulant, a radical polymerizable (alk) acrylic acid derivative, and optionally one or more radically polymerizable ethylenically unsaturated comonomers. Making; And (b) radically polymerizing the radically polymerizable (alk) acrylic acid derivative and optionally one or more radically polymerizable ethylenically unsaturated comonomers to obtain an intercalation polymer, wherein the polymer coagulant is (alk) acrylic Derived from at least one cationic monomer selected from the group consisting of amidoalkyltrialkyl ammonium halides, (alk) acryloyloxyalkyl trialkyl ammonium halides and alkenyl trialkyl ammonium halides A method for producing a heavy water polymer dispersion. |
