The invention is entitled "Melt Emulsion Extrusion Process for Preparing Thermoplastic Polymer Particles". Disclosed is a method for preparing thermoplastic polymer particles, which may comprise: mixing a mixture comprising a thermoplastic polymer and a carrier fluid immiscible with the thermoplastic polymer in an extruder at a temperature higher than the melting point or softening temperature of the thermoplastic polymer and at a sufficiently high shear rate to disperse the thermoplastic polymer in the carrier fluid; cooling the mixture below the melting point or softening temperature of the thermoplastic polymer to form solidified particles comprising thermoplastic polymer particles with a roundness of 0.90 or higher; and separating the solidified particles from the carrier fluid.
