Abstract:
A method including first grinding, in aqueous media of natural calcium carbonate, an acrylic polymer having a molecular weight of between 8,000 g/mole and 15,000 g/mole and a molar content of less than 20% of polymeric chains of molecular weight less than 3,000 g/mole and second, optionally concentrating, leading to an aqueous suspension with an increased slope factor, which improves the opacity of the coated paper produced from such a suspension.
