Abstract of the Disclosure Polymerizable ethylenically unsaturated urea-urethane polymer dispersions are prepared. In preparing the dispersions a polyisocyanate is contacted with a polyfunctional amine containing primary and/or secondary amino groups in the presence of: (a) a polyol free of ethylenic unsaturation, (b) a diluent, and (c) an active hydrogen-containing polymerizable ethyl- enically unsaturated compound under conditions sufficient to form a polymerizable ethylenically unsatu- rated urea-urethane compound dispersed in the polymerizable ethylenically unsaturated compound. The dispersions are useful in the formulation of in-mold coating compositions and injection molding compositions.
