Abstract

L’invention concerne un copolymère épaississant et sa méthode de préparation continue par extrusion réactive. La méthode de préparation comprend d’abord une réaction de polymérisation d’un composé dihalogéné et d’un monomère polyhydroxylé puis la réaction avec un composé hydrophobe monohalogéné. Ce copolymère permet de contrôler la viscosité d’une composition aqueuse.The invention relates to a thickening copolymer and its continuous reactive extrusion preparation method. The preparation method first comprises a polymerization reaction of a dihalogenated compound and a polyhydroxylated monomer, followed by a reaction with a hydrophobic monohalogenated compound. This copolymer allows for viscosity control of an aqueous composition.
