Polycarboxylic acid thickeners, emulsifiers, and suspending aids having improved wettability characteristics

摘要

A polymeric thickener, emulsifier or suspension aid having improved wettability which is an interpolymer of at least one olefinically unsaturated carboxylic acid containing at least one activated carbon-to-carbon olefinic double bond and at least one carboxyl group, in an amount of more than 15% by weight based upon the weight of the interpolymer, and at least one steric stabilizer surfactant having at least one hydrophilic moiety and at least one hydrophobic moiety and a linear block or a random comb configuration, or mixtures thereof, where the interpolymer has admixed therewith a wetting additive such as a low surface tension surfactant, a glycol, a polyhydric alcohol or mixtures thereof, and a process for dispersing the interpolymer by adding a low surface tension surfactant to the water into which the interpolymer is being dispersed.
