Abstract
An improved process for pruducing stabilized, core-shell latex emulsions is disclosed. In a process which comprises preparing a hydrophilic polymer and contacting the hydrophilic polymer with a hydrophobic monomer for producing an inverted core-shell latex emulsion, the improvement comprises the additional step of adjusting the pH of the inverted core-shell latex emulsion to dissolve the hydrophilic polymer, thereby to produce a stabilized, core-shell latex emulsion.
