ABSTRACT:
Hybrid polymers of epoxy resins are provided by polymerizing ethylenically unsaturated monomer in the presence of epoxy resin using a combination of oil soluble and water soluble surfactants in separate organic and aqueous phases, respectively, made up prior to combining under polymerizing conditions. The organic phase contains the monomer and epoxy resin and oil soluble surfactant while the aqueous phase contains water and the water soluble surfactant. Initiator systems can be included in the organic phase or added independently to the reaction mixture. The resulting hybrid epoxy polymer exhibits excellent properties when applied as a protective film or adhesive, and aqueous dispersions of the polymer can be compounded with polyfunctional amine curatives and still remain stable for long periods of time, making a convenient one-pack system that can be cured on application, drying and heating at a relatively low temperature.
