ABSTRACT OF THE DISCLOSURE This invention relates to a polymerization reaction vessel having a coating on the inner surfaces thereof resulting from applying thereto a coating composition containing, as a primary ingredient, a straight chain or branched poly- aromatic amine dissolved in an aqueous alkali metal hydroxide solution. When polymerizing olefinic monomers, such as vinyl halides, vinylidene halides, and vinylidene monomers having at least one terminal Image grouping, and mixtures thereof, in the presence of said coating, polymer build-up on the inner surfaces of the reaction vessel is substantially eliminated. Further, 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 to the atmosphere.
