Abstract: The invention comprises a novel process for producing an anti-scaler coating for monomer polymerization reactors comprising mixing hydroxymethansulphincal acid with 1-naphthol. The invention also comprises an anti-scaling product obtained by this novel process.

Abstract: The object of the invention is to provide a liquid anti-scaler for coating polymerizing reactors obtained by a condensation reaction of naphthol with an aldehydic cross-linking product, wherein the cross-linking product is the reaction product of hydrosulfite and formaldehyde. It contains hydrosulfite and/or radical bisulfites and/or bisulfite. The condensate is made in such a way that in the absence of oxygen, it is in the form of liquid of clear transparent color.

Abstract: According to the invention, there are provided a novel process for preparing an anti-scaling coating on the walls of a polymerization vessel by using aromatic compounds reacted with sodium hydroxymethanesulphinate, and an anti-scaling coating obtained by this novel process.

Abstract: This invention relates to a process for producing an anti-scaler product for coating polymerization reactors comprising condensing a naphthol with an aldehydic cross-linking agent, wherein the cross-linking agent is the reaction product of an aldehyde and a hydrosulphite.
