ABSTRACT:
A process for the preparation of anionic thermosetting resin emulsions, comprising the steps of (1) reacting an isocyanate-terminated urethane prepolymer with an excess of a polyalkylene-polyamine to form a polyurethane-urea-polyamine, (2) then reacting the thus-formed polyurethane-urea-polyamine with an epihalohydrin, (3) reacting the resulting reaction product of step (3) with a cyclic dicarboxylic acid anhydride, and then (4) mixing the resulting reaction product of step (3) with an aqueous solution of a basic substance to form an emulsion.
