Abstract:
The present invention concerns weakly anionic polymers including their use in paper coatings, especially those intended for paper for inkjet printing. These additives provide the sought thickening function, while improving water retention very appreciably. The invention also concerns a method of manufacture of such coatings, together with the coatings obtained in this manner.
Abstract:
New associative thickening agents belonging to the category of HASEs (Hydrophobically modified Alkali-Soluble Emulsions). These products contain an original associative monomer with a base of alkylcyclohexanol akoxylates. Their thickening power is greater than the HASE associative thickening agents of the prior art containing grafted alkyl phenols. An efficient substitute product is therefore available, which is free of alkyls phenols, matching current market demand.
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.
Abstract:
The present invention concerns new associative thickening agents belonging to the category of HEURs (Hydrophobically modified Ethylene oxide URethane). These products contain an original associative monomer with a base of alkyl cyclohexanol alkoxylates. Their thickening power is equal to or greater than that procured by HEUR associative thickening agents of the prior art containing grafted alkyl phenols. An efficient substitute product is therefore available, which is free of alkyl phenols, matching current market demand.

Abstract:
The present disclosure relates to a method for improving the auto-dispersant characteristic in water of a mineral substance. The method includes the steps of dry-grinding, in the presence of a formulation, a mineral substance selected from a dolomite, talc, titanium dioxide, alumina, kaolin and calcium carbonate, wherein the formulation contains a polyglycerol and no glycerol.
Abstract:
Emulsions containing acrylic associative thickening agents which, when polymerized in the presence of particular polyglycerols, have a thickening power which is remarkably stable over time.
Abstract:
The invention relates to the use of a comb polymer for preparing a slurry, said slurry comprising calcium carbonate, the viscosity of said aqueous slurry as measured by a HAAKE Rheostress rheometer ranging from 25 to 1000 mPa·s measured at 20° C. and at 90° C.
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 in 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, and traces of brushes and filling-knives.
