Hybrid polymer, aqueous dispersions and coating composition therefrom.

摘要

A hybrid polymer of a core/shell structure is provided which is based upon (A) a polymer (core) of an unsaturated fatty acid group functionalized poly(epoxyester) onto which (B) at least one addition polymer-based chain (shell) has been grafted. Also provided are aqueous dispersions of these hybrid polymers and coating compostions therefrom, which coating compositions are especially suited for use as clear coatings, pigmented coatings and primers/surfacers.
