Abstract

The present invention relates to a method for producing mineral particles grinding a mineral material in the presence of a specific anionic polymer. The polymer used is obtained by means of polymerisation in the presence of sodium hypophosphite, disodium dipropionate trithiocarbonate and at least one radical-generating compound. The invention also relates to an aqueous composition comprising particles of ground mineral material and such a polymer, in particular a paper coating slip composition.
