Abstract

This invention relates to a polymerization reaction vessel having a coating on the inner surfaces thereof resulting from applying thereto an aqueous coating solution of an alkali metal or ammonium salt of the reaction product or oligomers of an aromatic aldehyde, such as benzaldehyde, and the like, and a polyhydric phenol, such as resorcinol, and the like. When polymerizing olefinic monomers, such as vinyl halides, vinylidene halides, and vinylidene monomers having at least one terminal CH.sub.2 .dbd.CH< group, and mixtures thereof, while a contact with said coating, polymer buildup on the inner surfaces of the reaction vessel is substantially eliminated.
