Title (EN) SOLUTION POLYMERIZATION IN ISOPROPANOL AND WATER
(FR) POLYMÉRISATION EN SOLUTION DANS DE L'ISOPROPANOL ET DE L'EAU
Abstract:
(EN) A method for solution polymerization. The method comprises polymerizing in a solvent a monomer mixture comprising: (a) 5 to 95 wt% of a C3-C5 ethylenically unsaturated dicarboxylic acid; and (b) 5 to 95 wt% of vinyl acetate; wherein the solvent comprises 51 to 88 wt% isopropanol and 12 to 49 wt% water.
(FR) L'invention concerne un procédé de polymérisation en solution. Le procédé consiste à polymériser, dans un solvant, un mélange de monomères comprenant : (a) de 5 à 95 % en poids d'un acide dicarboxylique éthyléniquement insaturé en C3-C5 ; et (b) de 5 à 95 % en poids d'acétate de vinyle ; le solvant contenant de 51 à 88 % en poids d'isopropanol et de 12 à 49 % en poids d'eau.
