Abstract
Compositions and methods for forming surfactants, aqueous dispersions, and curing agents are provided. In one aspect, the invention relates to improved epoxy functional surfactants prepared by reaction of an epoxy composition and an amidoamine composition formed from a blend of acid-terminated polyoxyalkylene polyols. The improved epoxy functional surfactants may be reacted with an excess of epoxy composition and water to result in an aqueous dispersion. The amidoamone composition may be a reaction mixture of a diamine compound and an acid terminated polyoxyalkylene composition formed from two or more polyoxyalkylene polyol compounds. The epoxy functional surfactant may be reacted with amine compounds to form a compound suitable as a curing agent.
