| 20110105670 | PROCEDURE FOR MANUFACTURE OF AQUEOUS SUSPENSIONS OF CALCIUM CARBONATE AND SUSPENSIONS OBTAINED, AND THEIR USES - The object of the invention consists of a process for the manufacture of aqueous suspensions of calcium carbonate using an acrylic polymer with an average by weight 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. It also concerns the aqueous suspensions obtained, possibly dried, and their uses in the paper, paint, plastics and mastics industry. | 05-05-2011 |

| 20090270543 | Method of Producing an Impact-Resistant Thermoplastic Resin - The invention concerns a process to manufacture a thermoplastic resin charged with mineral or carbonated matter, and possibly containing an organic impact modifier, through the introduction into the said resin of a comb polymer with at least one ethylenic unsaturation monomer, to which is grafted at least one polyalkylene oxide function. The resins then obtained which also form the subject of the invention have an improved impact resistance without their rigidity being degraded. | 10-29-2009 |

| 20100133195 | SURFACE-REACTED CALCIUM CARBONATE IN COMBINATION WITH HYDROPHOBIC ADSORBENT FOR WATER TREATMENT - The present invention relates to a process for reducing the amount of organic components in water, wherein a surface-reacted naturalcalcium carbonate and a hydrophobic adsorbent, selected from the group consisting of talc, hydrophobised calcium carbonate, hydrophobised bentonite, hydrophobised kaolinite, hydrophobised glass, or any mixture thereof, are brought into contact with the water to be purified, the surface-reacted natural calcium carbonate being the reaction product of a naturalcalcium carbonate with an acid and carbon dioxide, which is formed in situ by the acid treatment and/or supplied externally, and the surface-reacted natural calcium carbonate being prepared as an aqueous suspension having a pH of greater than 6.0, measured at 20° C. | 06-03-2010 |
| 20100135886 | Treatment of Talc in a Solvent - The present invention is directed to a process for the treatment of talc, comprising the steps of (a) providing a talc having a first brightness value B1, measured according to ISO 2469, and forming a suspension of the talc in a liquid phase, the liquid phase of the suspension comprising at least one organic solvent, (b) delaminating and/or reducing the weight median particle size d | 06-03-2010 |

| 20100258258 | USE OF A SURFACE-REACTED CALCIUM CARBONATE IN TISSUE PAPER, PROCESS TO PREPARE A TISSUE PAPER PRODUCT OF IMPROVED SOFTNESS, AND RESULTING IMPROVED SOFTNESS TISSUE PAPER PRODUCTS - The present invention relates to the use of a surface-reacted natural calcium carbonate as filler in tissue paper products, to a process to prepare tissue paper products, and to a tissue paper product featuring an improved softness, wherein said surface-reacted natural calcium carbonate is the reaction product of a natural calcium carbonate with an acid and carbon dioxide, which is formed in situ by the acid treatment and/or supplied externally. | 10-14-2010 |
| 20110097311 | COMPOSITION HAVING BIOCIDE ACTIVITY FOR AQUEOUS PREPARATIONS - The present invention refers to a process for bacterial stabilizing aqueous preparations like e.g. calcium carbonate slurries and a composition which can be used for the biocidal treatment of such aqueous preparations. | 04-28-2011 |
| 20110146931 | COMPOSITIONS OF CALCIUM CARBONATES/PIGMENTS FOR PAPER FORMULATIONS, SHOWING PRINT THROUGH REDUCTION - The present invention relates to mixtures of two distinct porous, stable aggregates and rather coarse PCCs (precipitated) calcium carbonate pigments (such as a composition comprising a blend or mix of one of the two Grade B or Grade C PCCs, in combination with a second, specific S-PCC (S=scalenohedral type PCC) pigment in a ratio appropriately selected between 90/10 and 10/90 percent by dry weight, namely 80/20 and 20/80, with a coarser, third component, which may be a pigment and/or a filler such as natural calcium (ground) carbonate or (most preferably) a PCC (precipitated calcium carbonate), depending on the granulometry of the two fine PCCs the third, coarser component, may be omitted. The main criteria for selecting the said “coarser” pigment is that it should feature a granulometry which does no affect noticeably, when in admixture with the blend PCC Grade B (or PCC Grade C) with S-PCC the finest part of the granulometry data of the blend, and in particular that it should not contribute anything significant to the amount of particles <0.2 μm, preferably nothing <0.3 μm, more preferably nothing <0.5 μm and most preferably nothing <1 μm. | 06-23-2011 |
