20110054075 | Dispersants From Linear Polyurethanes - The present invention provides a non-aqueous composition containing a particulate solid, an organic medium and polyurethane dispersant with a substantially linear anchoring segment pendant tertiary amine group(s) from said anchoring segment and terminally attached solvent-solubilising terminal chains of a polyester, polyether, or polyacrylate including mixtures of such terminal chains. | 03-03-2011 |
20130041071 | DISPERSANT COMPOSITION - The invention relates to a composition containing a polyepoxide with polyether lateral chains and pendant hydrocarbyl groups. The invention further relates to a composition containing a particulate solid, an organic or aqueous medium, and a polyepoxide with polyether lateral chains and pendant hydrocarbyl groups. The invention further relates to novel compounds, and the use of the polyepoxide with polyether lateral chains and pendant hydrocarbyl groups as a dispersant. | 02-14-2013 |
20140024749 | Polymer and Compositions Thereof - The invention relates to a composition containing a polymer obtained by polymerising (1) a mono-vinyl monomer with one or more carboxylic acid groups to form a polymer with at least 2 to 200, or 5 to 150, or 10 to 100, or 15 to 50 repeat units, and (2) reacting the polymer of (1) with a primary hydrocarbyl amine and polyoxyalkylene primary amine (typically polyetheramine). The invention further relates to a composition containing a particulate solid, a liquid medium, and the polymer. The invention further relates to the use of the polymer as a dispersant. | 01-23-2014 |

20080227945 | Polyurethane Based Pigment Dispersants Which Contain Reactive Double Bonds - Polymeric urethane dispersants with solubilizing polymer chains and with reactive carbon to carbon double bonds are described. The reactive double bonds facilitate molecular weight build-up of the dispersant on dispersed particles (enhancing colloidal stability) or enhance the ability of the dispersants to be crosslinked into a matrix material. | 09-18-2008 |
20100093926 | Polyurethane Based Pigment Dispersants Which Contain Reactive Double Bonds - Polymeric urethane dispersants with solubilizing polymer chains and with reactive carbon to carbon double bonds are described. The reactive double bonds facilitate molecular weight build-up of the dispersant on dispersed particles (enhancing colloidal stability) or enhance the ability of the dispersants to be crosslinked into a matrix material. | 04-15-2010 |
20100152339 | Graft Copolymer And Compositions Thereof - The invention relates to a graft copolymer with a polyester side chain and at least one quaternised tertiary amine group. The tertiary amine may be aliphatic, aromatic or heterocyclic. The invention further relates to the use of the compound as a dispersant, particularly for pigments. | 06-17-2010 |
20100324206 | Dispersants - The present invention provides a non-aqueous composition containing a particulate solid, an organic medium and a polyurethane dispersant having laterally attached pendant groups with tertiary amine group(s), an essentially linear backbone and laterally attached solvent-solubilising side chains of a polyester or polyether including mixtures of such side chains. | 12-23-2010 |
