ABSTRACT:
A method of making an acrylic microgel resin which comprises preparing an aqueous microgel emulsion of an acrylic resin which is crosslinked with a multifunctional crosslinking agent, removing water from the emulsion by coagulation and/or azeotropic distillation with an organic solvent in which the microgel is insoluble and which forms an azeotrope with water, and incorporating the thus dehydrated microgel into an acrylic resin which has been prepared by solution polymerization in organic solvent.
