ABSTRACT:
Polymeric microparticles and dispersions of polymeric microparticles in a liquid hydrocarbon are disclosed. The dispersions are prepared by reacting in dispersed form a preformed NCO-prepolymer containing a segment solvated by the liquid hydrocarbon and a segment insoluble in the liquid hydrocarbon with an active hydrogen-containing compound. Reaction proceeds to form polymeric microparticles which are dispersed in the liquid hydrocarbon. Also disclosed are the use of the polymeric microparticles in coating compositions and articles coated with the coating compositions.
