CA 2639923

The invention relates to a method for controlling the thickening of aqueous, silicate-containing systems, characterized in that at least one copolymer having an average molecular weight (Mw) of at least 3000 g/mol and not more than 60000 g/mol is added to said aqueous system and that the copolymer is, essentially statistically, made of monoethylenically unsaturated monocarboxylic acids, monoethylenically unsaturated dicarboxylic acids and eventually ethylenically unsaturated comonomers. The method is also characterized in that the polymerization is carried out in the presence of 0.01 to 100 mol-%, in relation to the total amount of all COOH groups of the mono- and dicarboxylic acids, of at least one base for producing the copolymer, the indicated amounts in wt.-% each referring to the total amount of all used monomers.

L'invention concerne un procédé pour contrôler l'épaississement de systèmes aqueux contenant des silicates. Ce procédé se caractérise en ce qu'il consiste à ajouter au système aqueux au moins un copolymère d'un poids moléculaire moyen Mw d'au moins 3 000 g/mole et d'au maximum 60 000 g/mole puis à constituer le copolymère de manière sensiblement statistique à partir d'acides monocarboxyliques monoéthyléniquement insaturés, d'acides dicarboxyliques monoéthyléniquement insaturés et éventuellement d'autres comonomères éthyléniquement insaturés et en ce qu'il consiste à réaliser la polymérisation en présence de 0,01 à 100 % en mole d'au moins une base, par rapport à la quantité totale de tous les groupes COOH des acides mono- et dicarboxyliques, pour produire le copolymère, les quantités indiquées en pourcentage en poids se rapportant chacune à la quantité totale de tous les monomères utilisés.
