A process comprising:
- dissolving a polymer in an organic solvent to form a polymer solution;
- and
- forming a latex from the polymer solution by contacting the polymer solution with steam while substantially simultaneously distilling the organic solvent.
A process comprising:
- forming a polyester solution by dissolving a polyester in an organic solvent;

A system comprising:
- a reaction vessel configured to introduce steam into the reaction vessel, the reaction vessel also being configured to perform distillation in vacuo while concurrently introducing steam into the reaction vessel;
- a steam generator configured to be in fluid communication with the reaction vessel;
- and
- a vacuum pump configured to be in fluid communication with the reaction vessel and to modulate the pressure while concurrently introducing steam into the reaction.
