The object of the invention is to provide an anti-scaler for coating the polymerizing reactors for monomers, of the liquid types, obtained by means of the naphthols condensation with analdehydic cross-linking product, characterized by that: for obtaining the condensate a hydrosulphite is used; it contains hydrosulphite and/or radical bisulphites and/or bisulphite; the condensate is made in such a way that in absence of oxygen, it is in the form of liquid of clear transparent colour.

L'invention concerne un agent anti-tartre servant à revêtir les réacteurs de polymérisation de monomères de type liquide et qu'on obtient au moyen de la condensation de naphtols avec un produit de réticulation à base d'analdéhyde, caractérisé par le fait qu'on utilise un hydrosulfite afin d'obtenir le condensat; qu'il contient un hydrosulfite et/ou des bisulfites radicaux et/ou du bisulfite. Le condensat est constitué de telle façon qu'en l'absence d'oxygène, il se présente sous la forme d'un liquide de couleur claire et transparente.
