Disclosed is a method of inhibiting the formation of scale on reactor surfaces in contact with a polymerizing vinyl monomer comprising contacting said monomer with a terpolymer which comprises the condensation reaction product of (A) an aromatic compound that contains the group (I) or (II) where Q is OR or SR and R is hydrogen, alkyl from C1, to C15, or aryl, alkaryl, or aralkyl from C6 to C15 (B) about 0.1 to about 10 moles of a carbonyl compound per mole of said aromatic compound; and (C) about 0.1 to about 10 moles of a thiourea per mole of said aromatic compound.

L'invention concerne un procédé inhibant la formation de dépôts sur les surfaces d'un réacteur au contact d'un monomère vinylique en polymérisation, consistant à mettre en contact ledit monomère avec un terpolymère comprenant le produit de réaction de condensation de (A) un composé aromatique contenant les groupes (I) ou (II) dans lesquels Q représente OR ou SR et R représentent hydrogène, alkyle C¿1? à C¿15? ou aryle, alkyle ou aralkyle C¿6? à C¿15?, (B) environ 0,1 à environ 10 moles d'un composé de carbonyle par mole dudit composé aromatique; et (C) environ 0,1 à environ 10 moles d'une thiourée par mole dudit composé aromatique.
