| 摘要 |
The present invention relates to the production of aqueous solutions or dispersions of high molecular weight, high solids copolymers of aliphatic dicarboxylic acids, especially maleic acid, with .alpha.,.beta.-ethylenically unsaturated monomers having carboxyl or sulfonic acid groups, such as (meth)acrylic acid or 2-acrylamido-2-methyl propane sulfonic acid (AMPS), respectively, which solutions or dispersions have a very low residual content of unpolymerized dicarboxylic acid monomer.
