Abstract

See full text

A method of producing thermoplastic particles may comprise: 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 a temperature greater than a melting point or softening temperature of the thermoplastic polyester and at a shear rate sufficiently high to disperse the thermoplastic polyester in the dispersed phase; and cooling the melt emulsion to below the melting point or softening temperature of the thermoplastic polyester to form solidified particles comprising the thermoplastic polyester.
