ABSTRACT:
Aqueous dispersions of film-forming polymer particles are prepared by first forming a cationically or anionically stabilized dispersion in water of a solution of preformed polymer or polymer plasticizer in initial polymerizable monomer; then polymerizing the monomer and forming disperse polymer particles; and thereafter adding further polymerizable monomer which is then polymerized. The Tg of polymer prepared from the further monomer is higher than that of polymer prepared from the initial monomer. The polymer dispersions are useful in providing thick electrodeposited coatings.
