Thermoplastic polyester particles and methods of production and uses thereof

A method comprising:

• mixing a melt emulsion comprising (a) a continuous phase that comprises a carrier fluid having a polarity Hansen solubility parameter (dP) of about 7 MPa0.5 or less, (b) a dispersed phase that comprises a dispersing fluid having a dP of about 8 MPa0.5 or more, and (c) an inner phase that comprises a thermoplastic polyester at about 200° C. to about 320° C. and at a shear rate sufficiently high to disperse the thermoplastic polyester in the dispersed phase, wherein the thermoplastic polyester comprises a member selected from the group consisting of polybutylene terephthalate (PBT), polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polytrimethylene terephthalate (PTT), polyhexamethylene terephthalate, and any combination thereof;
• and
• cooling the melt emulsion to below 160° C. to form solidified particles comprising the thermoplastic polyester.
