ABSTRACT:
N-acylated aminohydrocarbyl sulfonic acids or acid derivative compositions are described which are characterized by the presence with the structure of at least one acyl, acylimidoyl or acyloxy group attached to the amino nitrogen, said groups being derived from at least one of the carboxylic acid groups contained in an interpolymer of (i) at least one vinyl aromatic monomer and (ii) at least one alpha, beta-unsaturated acid or derivative thereof. Aqueous systems also are described which comprise at least about 40% of water and the N-acylated amino hydrocarbyl sulfonic acid or salt composition of the invention. The hydrocarbyl sulfonic acid or salt compositions of the present invention are useful as emulsifiers, thickeners, dispersants, etc. in the aqueous systems, and the compositions also are useful as additives in fuels and lubricants.
