ABSTRACT:
Anionic water soluble carboxyl-containing polymers, deposited and dried on polymerization reactor surfaces exposed to polymerization mixtures, substantially reduce or eliminate undesirable polymer build-up on reactor surfaces during aqueous polymerization of vinylidene monomers, even when the amount of carboxyl-containing polymers deposited on the reactor surfaces is in an amount as small as at least one ppm of monomers being polymerized, providing a layer on the polymerization surfaces as thin as about 0.1 to about one or more microns in thickness.
