Abstract

Abstract A dispersion of two different types of graft copolymers in an organic liquid. One of the types has a polymeric diene backbone component and a nitrile graft component; the other type has an unsaturated polymer backbone component and a graft component which is a polymer of a graft copolymerizable vinyl monomer. The dispersion is useful as a coating composition, particularly for coating cans.
