Abstract: front page image
(EN)A dispersant is provided comprising a blend of mono- and di-phosphate esters, each phosphate group being substituted with either one or two alkyl or alkenyl alkoxylate groups wherein the alkyl or alkenyl portion is a branched alkyl or alkenyl radical comprising 1-30 carbon atoms, the alkoxylate portion comprises ethoxylate monomers and/or propoxylate monomers, and the dispersant further comprises a basic component selected from an amidopropyldimethylamine, a heterocyclic amine, an ammonium ion, and an alkali metal ion. The dispersant is suitable for dispersing a variety of pigments and other particulate matter in either aqueous or organic media.
(FR)L'invention concerne un dispersant comprenant un mélange de mono-et di-esters de phosphate, chaque groupe phosphate étant substitué par un ou deux groupes d'alcoxylate d'alkyle ou alcényle, la partie alkyle ou alcényle étant un radical alkyle ou alcényle ramifié comprenant de 1 à 30 atomes de carbone, la partie d'alcoxylate comprenant des monomères éthoxylate et/ou des monomères propoxylate, et le dispersant comprenant également un composant de base sélectionné à partir d'un amine hétérocyclique, un amidopropyldimethylamine, un ion ammonium et un ion de métal alcalin. Le dispersant est adapté pour disperser une variété de pigments et d'autres matières particulaires dans des milieux aqueux ou organiques.
