ABSTRACT:
Spheres of cured vinyl ester resin of a size useful as a flattening agent in paper coating compositions are prepared by a process of adding an aqueous phase containing polyvinyl alcohol to a stirred vinyl ester resin phase containing a free-radical catalyst to form a resin-in-water dispersion followed by addition of a promoter and the resin allowed to cure.
