ABSTRACT:
The use of a cyclic compound containing a ##STR1## group, i.e., methone, has been found to allow a poor acrylamide or acrylic acid or 2-acrylamide-2-methylpropane sulfonic acid and its salts monomer to be polymerized to a polymer having improved performance characteristics and/or improved rates of polymerization. Optionally, urea is added with the methone.
