Patent ID: 8191807

Claim:
A method for manufacturing self-binding particles comprising: grinding at least one latex binder and at least one mineral material in an aqueous medium, in the presence of an aqueous solution of a fully or partially acidic, water-soluble copolymer as coupling agent, wherein: the aqueous solution of a fully or partially acidic, water-soluble copolymer is added to the aqueous medium before and/or during the grinding step, and the aqueous solution of a fully or partially acidic, water-soluble copolymer comprises: a) of at least one ethylenically-unsaturated anionic monomer, b) at least one ethylenically-unsaturated oxyalkylated monomer terminated by a hydrophobic alkyl, alkylaryl, arylakyl, or aryl chain having 10 to 32 carbon atoms, and c) optionally, at least one other monomer.
