Abstract
PROCEDE DE PREPARATION D'ETHERS POLYGLYCIDIQUES LIQUIDES DE PHENOLS POLYHYDRIQUES. ON PREPARE DES ETHERS POLYGLYCIDIQUES LIQUIDES DE PHENOLS POLYHYDRIQUES: A.EN FAISANT REAGIR LE PHENOL POLYHYDRIQUE AVEC UN EXCES D'EPICHLORHYDRINE EN PRESENCE D'UN HALOGENURE IONISABLE SOLUBLE COMME CATALYSEUR DE CONDENSATION A DES TEMPERATURES COMPRISES ENTRE 60 ET 130C; B.EN DILUANT LE PRODUIT DE L'ETAPE A AVEC 40 A 80 DE SON POIDS D'UN SOLVANT ORGANIQUE SOLUBLE DANS L'EAU ET EVENTUELLEMENT D'EAU ET EN LE FAISANT REAGIR EN UNE SEULE OU PLUSIEURS ETAPES AVEC UNE SOLUTION AQUEUSE D'UN HYDROXYDE DE METAL ALCALINA DES TEMPERATURES INFERIEURES A 65C, LA QUANTITE D'EAU ETANT SUFFISANTE POUR MAINTENIR EN SOLUTION AQUEUSE L'HALOGENURE DE METAL ALCALIN FORME, EN SEPARANT LA SAUMURE ET C.EN RECUEILLANT L'ETHER POLYGLYCIDIQUE. L'INVENTION PERMET D'OBTENIR UN MEILLEUR RENDEMENT.
