METHOD OF PREPARING AQUEOUS SUSPENSIONS OF MINERAL MATERIALS OR DRIED MINERAL MATERIALS, OBTAINED PRODUCTS AND USE THEREOF Russian patent published in 2013 - IPC C09C1/02 C09C3/10 C08K3/26 D21H17/67 D21H19/38 C01F11/18 

FIELD: chemistry.

SUBSTANCE: invention can be used in chemical, paint and paper industry. Aqueous mineral materials are prepared by a) providing at least one mineral material in the form of an aqueous suspension or in dry form, b) providing at least one partially or completely lithium-neutralised water-soluble organic polymer selected from a group of homopolymers of acrylic or methacrylic acid and/or copolymers of acrylic and/or methacrylic acid with one or more acrylic, vinyl or allyl monomers, wherein the molar ratio of non-neutralised acid groups is in the range of 0-10%, c) combining the at least one partially or completely lithium-neutralised water-soluble organic polymer from step b) with at least one mineral material from step a). The obtained mineral materials or aqueous suspensions thereof are used in making paper, plastic and paint.

EFFECT: invention enables to obtain material having a stable pH, low Brookfield viscosity, which remains stable over time, and requires low content of dispersant and/or grinding enhancer.
