Abstract

L'INVENTION EST RELATIVE A UN PROCEDE POUR PREVENIR LA FORMATION DE DEPOTS DE POLYMERE SUR LES PAROIS DU REACTEUR DANS LES PROCEDES DE POLYMERISATION DE MONOMERES ETHYLENIQUEMENT INSATURES DANS UN MILIEU AQUEUX, CARACTERISE EN CE QU'AVANT L'INTRODUCTION DU MONOMERE, DE L'EAU ET DES AUTRES INGREDIENTS NECESSAIRES POUR LA POLYMERISATION, ON APPLIQUE SUR LES SURFACES DES PAROIS DU REACTEUR DE POLYMERISATION UNE SOLUTION AQUEUSE CONTENANT: A.UN COLORANT ANIONIQUE HYDROSOLUBLE; B.UN COLORANT CATIONIQUE HYDROSOLUBLE; ET C.UNE ALKYLAMINE SECONDAIRE OU TERTIAIRE DANS LAQUELLE CHACUN DES GROUPES ALKYLE POSSEDE DE 1 A 6ATOMES DE CARBONE ET SECHE LA SURFACE AINSI REVETUE.THE INVENTION RELATES TO A PROCESS FOR PREVENTING THE FORMATION OF POLYMER DEPOSITS ON THE WALLS OF THE REACTOR IN PROCESSES FOR THE POLYMERIZATION OF ETHYLENICALLY UNSATURE MONOMERS IN AN AQUEOUS MEDIUM, CHARACTERIZED BY BEFORE THE INTRODUCTION OF THE MONOMER, OF ' WATER AND OTHER INGREDIENTS NECESSARY FOR THE POLYMERIZATION, AN AQUEOUS SOLUTION CONTAINING: A. A WATER-SOLUBLE ANIONIC COLORANT IS APPLIED TO THE SURFACES OF THE WALLS OF THE POLYMERIZATION REACTOR; B. A WATER-SOLUBLE CATIONIC DYE; AND C. A SECONDARY OR TERTIARY ALKYLAMINE IN WHICH EACH OF THE ALKYL GROUPS HAS 1 TO 6 ATOMS OF CARBON AND DRIES THE SURFACE THUS COATED.
