Acrylic-polyurethane hybrid emulsions were prepared by converting amphiphilic acrylic-polyurethane graft copolymers previously synthesized in nonaqueous media by grafting vinyl monomers to partially vinyl-endblocked polyurethanes to aqueous emulsions. These emulsions were found to form core-shell st...
