Abstract
"USO DE áCIDOS POLIACRìLICOS, E, SUSPENSãO AQUOSA FINAMENTE DIVIDIDA DE CARBONATO DE CáLCIO". A invenção se refere ao uso de ácidos poliacrílicos os quais contêm grupos terminais orgânicos contendo enxofre, compreendendo pelo menos dois átomos de carbono, tendo um peso molecular médio M~ w~ de 5.000 a 30.000 g/mol e os quais são pelo menos parcialmente neutralizados por uma base a qual é selecionada do grupo de hidróxidos alcalinos e amónia como agentes auxiliares para moagem a úmido de carbonato de cálcio. A invenção também se refere a suspensões aquosas de partícula fina de carbonato de cálcio as quais são produzidas por moagem a úmido de carbonato de cálcio na presença de dito ácidos poliacrílicos.
