Polymerization reaction vessel having a coating on the interior surfaces resulting from the application of an aqueous coating solution of an alkali metal or ammonium salt of the reaction product or oligomers of an aromatic aldehyde, such as than benzaldehyde and the like, and a polyhydric phenol, such as resorcinol, and the like. During the polymerization of olefinic monomers, such as vinyl halides, vinylidene halides, and vinylidene monomers having at least one terminal group CH2 = CH <, and their mixtures, while being in contact with this coating, a polymer formation on the interior surfaces of the reaction vessel is substantially eliminated |
