ABSTRACT:
A process for polymerization of vinyl halide monomers in reactors with interior walls treated with a coating composition to prevent buildup said coating composition comprising a mixture of at least one compound chosen from the group consisting of monomeric aliphatic and aromatic amines, and at least one compound chosen from the group consisting of oxy-group substituted aromatic compounds and quinone type compounds. One embodiment is directed towards low temperature formation of the coating product in the presence of oxygen and on the reactor surface. Another embodiment concerns preforming the coating product and then applying it to the reactor surfaces.
