ABSTRACT:
A grinding agent containing polymers and/or copolymers partially neutralized by magnesium, for aqueous suspensions of mineral substances to be used in pigmentary applications is disclosed.
A grinding agent composed of polymers and/or copolymers having a specific viscosity of between 0.3 and 0.8 and obtained by treatment, using one or several solvents, of a polymer and/or copolymer resulting from polymerization and/or copolymerization of acrylic and/or vinyl monomers comprising acid groups whose active acid sites are partially or completely neutralized to a degree of neutralization of 40 to 60%, including terminals, of the active acid sites using a neutralizing agent containing magnesium ions, and a degree of neutralization reaching 60% using a neutralizing agent containing sodium ions is disclosed.
A procedure for grinding in an aqueous suspension using said agent, as well as aqueous suspensions produced using said procedure and their applications to the fields of weight fillers, paper coating, paints, and plastics is also disclosed.
