Title: Highly functionalized ethylene-vinyl acetate emulsion copolymers

Abstract: This invention relates to aqueous emulsion copolymers comprising from about 2% to about 20% of ethylene, from about 20% to about 78% of vinyl acetate, and from about 20% to about 60% of a functionalized monomer selected from the group consisting of acid containing monomers, nitrogen containing monoolefinically unsaturated monomers, and hydroxyl containing monomers. The present invention also pertains to methods for making the ethylene vinyl acetate aqueous emulsion copolymers containing high concentrations of functionalized monomers and to ethylene vinyl acetate aqueous emulsion copolymers made by the the novel methods.
