ABSTRACT:
A water-dispersible hybrid polymer of a core/shell structure is provided which is based upon (A) a polymer (core) of a mercapto-functionalized poly(epoxyester) onto which (B) at least one addition polymer-based chain (shell) has been grafted via the addition polymerization of free-radically polymerizable monomers in the presence of the mercapto-functionalized poly(epoxyester). Also provided are aqueous dispersions of these hybrid polymers and coating compositions therefrom, which coating compositions are especially suited for use as clearcoats and surfacers.
