Abstract
Compositions of salts of water-soluble, carboxyl-containing polymers and surface active agents, deposited 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 very small.
