    Abstract: Processes for making reactive surfactants are disclosed. In one such process, a fatty epoxide, a glycidyl ether, or a combination thereof is reacted with an olefin-functional nucleophile to produce an olefin-functional hydrophobe. The olefin-functional hydrophobe is reacted with ethylene oxide, propylene oxide, butylene oxides, or a combination thereof to produce an alkoxylate. Optionally, the alkoxylate is converted to the corresponding sulfate, phosphate, or maleate. Surfactant compositions comprising the reactive surfactants made by these processes are also described. The invention includes polymerizable mixtures comprising an acrylic monomer and the surfactant compositions as well as aqueous acrylic latex emulsions and coatings produced from the emulsions. The reactive surfactants deliver stable latex emulsions with reduced tendency for surfactant migration or excessive foaming. Coatings from the emulsions have improved wet adhesion, scrub resistance, and water resistance.

    Abstract: A film may be formed from film forming compositions which comprise at least one carboxamide based coalescing solvent. These coalescing solvents impart equivalent or improved wet-scrub resistance, block resistance, gloss, dirt pick-up resistance and leveling characteristics to the films on a substrate, without contributing to total VOC levels, when replacing conventional coalescing solvents. The present invention also includes a method for forming a film comprising applying a film forming composition comprising polyunsaturated reactive carboxamides to a substrate and curing the film under ambient conditions. The coalescing carboxamide solvents are suitable for paint, latex based caulk, adhesives and floor care applications.
