Abstract
Acidic monomers are polymerized in aqueous solutions containing a free radical initiating catalyst and a methylol amide reagent or formaldehyde. The resulting acidic polymers have very high molecular weight as measured by the viscosities of dilute solutions of the acidic and neutralized polymers. The reaction solutions can be used to form tough, insoluble films, and the polymers can serve as effective thickening agents and floculating agents.
