ABSTRACT:
Fluid coating materials such as paints, ink pastes, personal care creams and the like having a water-base are thickened with an associative thickener which is a vinylamine polymer having a weight average molecular weight above 10.sup.5 and which has been modified by reaction with at least 0.2 mer percent of a linear monoaldehyde having 8 to 30 carbon atoms. A hydrolyzed polymer of N-vinylformamide which has been hydrophobically modified with an aldehyde such as dodecaldehyde, exhibits associative thickening characteristics and is useful in thickening water-based formulations.
