Method of milling minerals in the presence of a poly (itaconate)
11578214 · 2023-02-14 · ·

The invention relates to a method for producing particles of mineral material comprising grinding of at least one mineral material in the presence of water. The grinding according to the invention is carried out in the presence of at least one polymer obtained by a radical polymerization reaction of a partial sodium salt of itaconic acid and partial decarboxylation of the polymer obtained followed by partial or total neutralization of the decarboxylated polymer. The invention also relates to an aqueous composition comprising particles of ground mineral material and such a polymer, in particular a mass-loading composition for the production of paper or a paper-coating-colour composition.
