20130245216 | SET-LRP POLYMERIZATION OF ACRYLATES IN THE PRESENCE OF ACIDS - SET-LRP polymerization of acrylic monomers under acidic conditions is described. The source of the acidity may be the solvent (e.g., an acetic acid-containing solvent) or in the monomer content (e.g., acrylic acid or methacrylic acid, optionally in combination with other monomers such as methyl methacrylate). | 09-19-2013 |
20140039115 | SULFONIC ACID MONOMER BASED COMPOSITIONS - The present invention relates to a composition which comprises a stable aqueous dispersion of discrete polymer particles and a water-soluble dispersant adsorbed onto the surfaces of pigment particles, wherein the polymer particles comprise structural units of a sulfonic acid monomer or a salt thereof. The present invention addresses a need in the art by providing a way to improve the hiding efficiency of compositions containing pigment such as TiO | 02-06-2014 |
20140039117 | SULFONIC ACID MONOMER BASED COMPOSITIONS - The present invention relates to a composition comprising a water-soluble dispersant comprising structural units of a sulfonic acid monomer or a salt thereof and a co-monomer. The dispersant of the present invention addresses a need in the art by providing a way to improve the hiding efficiency of coatings compositions. | 02-06-2014 |
20140121305 | COMPOSITION CONTAINING ASSOCIATIVE RHEOLOGY MODIFIER AND POLYMER ENCAPSULATED PIGMENT PARTICLES - The present invention relates to a composition comprising an associative thickener, a binder, polymer encapsulated opacifying pigment particles, and water.
