ABSTRACT:
A pourable, liquid antisettling composition comprises at least one low molecular weight copolymer of ethylene and an alpha, beta-ethylenically unsaturated carboxylic acid that has been neutralized with a neutralizing agent and water. The composition can be an additive in aqueous coating compositions and provides excellent pigment suspension and rheological properties to aqueous based coating and ink compositions.
