Abstract:
The invention pertains to the use as a coupling agent, in a method for manufacturing self-binding particles by grinding at least one latex binder and at least one mineral material in an aqueous medium, of an aqueous solution of a fully or partially acidic water-soluble copolymer, present during the step of grinding, wherein the copolymer is made up of at least one ethylenically-unsaturated anionic monomer, and at least one ethylenically-unsaturated oxyalkylated monomer terminated by a hydrophobic alkyl, alkylaryl, arylakyl, or aryl chain having 10 to 32 carbon atoms.
