| 摘要 |
<p>The invention relates to a liquid dispersant of the formula I wherein T is selected from a polyethylene imine (PEI) or modified PEI moiety, polyvinylamine (PVA) or modified PVA, or polyallylamine (PAA) or modified PAA. B is a branched monomer selected from a monofunctional carboxylic acid moiety having at least two hydroxyl groups or a monofunctional carboxylic acid moiety having at least two hydroxyl groups wherein one or more of the hydroxyl groups are hydroxyalkyl substituted, R1 and R2 independently of one another are hydrophobic groups selected from a saturated or unsaturated fatty acid moiety with 3-24 carbon atoms, a monofunctional carboxylic acid moiety or a polymer moiety containing C3-C24 alkyl (hydroxyl)carboxylic acid moieties with MW ranges from 100 to 10,000 g/mol, X is B with—OH terminal group, or R1 or R2, q is a number between 5-2000, with the proviso that q is less than the sum of all amine groups of PEI, PVA, PAA. n is a number of 1-6.</p> |
