Abstract

L'invention est relative à un procédé de polymérisation d'un monomère vinylique ou d'un mélange de monomères vinyliques dans un réacteur comportant une surface en contact avec le monomère ou le mélange de monomères, procédé caractérisé en ce que, avant la polymérisation, on revêt cette surface du réacteur d'un liquide de revêtement aqueux contenant au moins du sel la) alcalin ou d'ammonium de colorants anioniques hydrosolubles du type des acides sulfoniques ou des acides carboxyliques, le liquide ayant un pH ne dépassant pas 7, réglé au moyen d'un agent de réglage du pH, et que l'on sèche la surface ainsi revêtue.
