Abstract: An organic solvent-free phase-inversion emulsification process for a low molecular weight amorphous polyester resin includes forming a mixture by adding to the amorphous polyester resin: i. a surfactant; ii. an aqueous solution of a neutralizing agent; and iii. a portion of water that is about 40% or less of a total amount of water used to form a phase-inversion emulsion, heating the mixture to dissolve the amorphous polyester resin to provide a dissolved amorphous polyester and adding water up to the total amount of water to the dissolved amorphous polyester to form a latex of the amorphous polyester resin. The resultant latex is used in processes of making a toner composition. A latex of an amorphous polyester resins is made by such processes have latex particles that are unimodal.
