  • WEAKLY IONIC POLYMERS FOR AN AQUEOUS SUSPENSION OF MINERAL FILLERS FOR PAPER COATING COLORS INTENDED FOR INK JET PRINTING
    Publication number: 20130253117
    Abstract: The present invention provides weakly ionic polymeric additives that, when used in aqueous suspensions of commercial mineral fillers (dispersed with an anionic polymer), enable the introduction of organic or mineral salts in significant quantities without causing a destabilization of the medium. The suspension are useful in the formulation of a paper coating color designed for an application of the ink-jet type.

  • USE OF GLYCEROL AS AN AGENT TO IMPROVE THE SELF-DISPERSING PROPERTIES OF A MINERAL MATERIAL TO BE ADDED TO AN AQUEOUS COMPOSITION
    Publication number: 20130056566
    Abstract: The invention consists of the use, during a mineral substance dry-grinding step, of formulations containing glycerol and/or polyglycerols as agents for improving the auto-dispersing characteristic of the said mineral substance in an aqueous composition. The immediate viscosity of the final composition is thus lowered and maintained stable over the course of time. In addition, the amount of foam formed during the dispersion in water step is reduced.

  • USE OF A WEAKLY IONIC ACRYLIC POLYMER IN THE SYNTHESIS OF PRECIPITATED CALCIUM CARBONATE
    Publication number: 20110135560
    Abstract: The invention consists in the use, in a method to manufacture a mineral matter, notably a precipitated calcium carbonate, of a polymer consisting of at least one vinylic monomer chosen from among acrylic or methacrylic acid, acrylamide, methacrylamide or a cationic monomer, or their blends, and at least one non-ionic monomer. The use of this polymer enables the carbonation time of the PCC to be reduced, without however impairing its crystallographic structure and its granulometric characteristics.
