Patent ID: 8492065

Claim:
A process comprising: providing at least one polyester resin possessing at least one acid group in at least one extruder by conducting a polycondensation reaction by contacting at least one diacid with at least one diol and with an optional seed resin and optional initiator to form the polyester resin; wherein the polycondensation reaction occurs in the extruder at a temperature from about 200° C. to about 360° C.; neutralizing the at least one acid group by contacting the resin with a base selected from the group consisting of ammonium hydroxide, potassium hydroxide, sodium hydroxide, sodium carbonate, sodium bicarbonate, lithium hydroxide, potassium carbonate, triethyl amine, triethanolamine, pyridine, diphenylamine, poly(ethylene amine), and combinations thereof; emulsifying the neutralized resin by contacting the neutralized resin with an aqueous solution including at least one surfactant in the absence of a solvent to provide a latex emulsion containing latex particles; and continuously recovering the latex particles.
