Abstract
This invention relates to a polymerization reaction vessel having a coating on the inner surfaces thereof resulting from applying thereto an aqueous coating composition containing the reaction product of a thiodiphenol, or a derivative thereof, with a bleaching agent or material, such as, for example, sodium hypochlorite (NaOCl). When polymerizing olefinic monomers, such as vinyl halides, vinylidene halides, and vinylidene monomers having at least one terminal CH.sub.2 .dbd.C< group, and mixtures thereof, polymer buildup on the inner surfaces of the reaction vessel is substantially reduced. Multiple charges or batches of polymer can be made in said internally coated reaction vessel without opening the same between charges thus preventing the escape of unreacted monomer(s) to the surrounding atmosphere.
