Reverse transfer iodine polymerization of ethylenically unsaturated monomers comprising (meth)acrylic acid, its salts, or a combination thereof in the presence of a radical polymerization initiator, an oxidizing agent, an iodide salt, and a solvent is a method used in the manufacture of (meth)acrylic acid. based) useful method for acrylic polymers. In the presence of 1 to 3 equivalents of the radical polymerization initiator, 0.2 to 1 equivalent of the oxidizing agent, and 1 equivalent of the iodide salt, the amount of the components used may be 5 to 500 equivalents containing (methyl ) said ethylenically unsaturated monomers of acrylic acid, its salts, or a combination thereof. A (meth)acrylic polymer solution is produced by these methods. (Meth)acrylic polymers can be used as dispersants. |
