    Abstract: The present invention relates to new acrylic associative thickening agents which, when polymerized in the presence of particular polyglycerols, ultimately result in an increase of the open time of the paint or of the thick coating in which they are incorporated. By so doing, painters and applicators will have more time to work the paint layers gradually or to correct imperfections such as paint droplets, traces of brushes and filling-knives.

    Abstract: A method for reducing the hygroscopicity of a material (M) including calcium carbonate may include treating the calcium carbonate with at least one homopolymer grinding assistant (P) which is neutralized in a particular way. A method for producing such a material (M) including calcium carbonate may include treating the calcium carbonate with at least one homopolymer grinding assistant (P) to provide such a material (M), which is then of reduced hygroscopicity. Such a calcium carbonate may be used as a filler in polymeric plastics.

    Abstract: The invention relates to the field of preparing aqueous dispersions of organic, organometallic or inorganic particles. In particular, the invention relates to the preparation of aqueous suspensions comprising organic, organometallic or inorganic particles and at least one particular copolymer obtained by polymerization of at least one acid and at least one compound or at least one ester derived from a particular acid, in the presence of water, at least one initiator compound and at least one activator compound, followed by total or partial neutralization by means of at least one compound chosen from alkali metal hydroxides, alkaline earth metal hydroxides, alkaline earth metal dihydroxides and mixtures thereof. The invention relates to such a particular copolymer having a low polydispersity index and weight-average molecular weight, the preparation process thereof and the use thereof, especially for the preparation of an aqueous paint composition.

    Abstract: The invention relates to a process for preparing a dispersion of a lipophilic compound in a continuous hydrophilic phase, the morphology of which is submicronic. During the preparation of this dispersion, there is applied, by means of a device which produces a shearing gradient less than 5000 s−1, a shear stress from 100 to 5000 Pa during the addition of the lipophilic compound in the continuous phase which comprises a rheology-modifying compound selected from anionic copolymers, preferably an anionic polymer, in particular an ASE polymer or a HASE polymer. The dispersed particles of the lipophilic compound are nanometric particles whose size is less than 1 μm. The dispersion, particularly in the form of an emulsion, can be used in numerous fields.

    Abstract: The invention concerns the field of detergent compositions, in particular detergent compositions for automatic washing, in particular for automatic dishwashing. Therefore, the invention provides a phosphate-free detergent composition comprising at least one non-sulfonated, non-ionic surfactant compound and a non-sulfonated water-soluble copolymer prepared, by polymerisation reaction, in the presence of at least one compound comprising at least one alcohol function, acrylic or methacrylic acid and a compound of formula (I): The invention also concerns the use of this non-sulfonated water-soluble copolymer as an anti-scaling agent or anti-drip agent, and a cleaning method.
