Abstract: Neutralized, aqueous solutions of alkyd resins are used as the sole emulsifiers to stabilize emulsion polymers formed using vinyl monomers. A product emulsion system contains on a 100 weight percent total system non-volatile solids basis typically from about 25-50 weight percent alkyd resin with the balance being in situ emulsion polymerized vinyl monomers. Product emulsion systems are storage stable and can be coated or cast to form clear films, and paints formulated therefrom can display excellent gloss, leveling and water resistance qualities.
