Claim 15:
16. A method comprising:
providing a mixture comprising a thermoplastic polymer, a nucleating agent, a carrier fluid that is immiscible with the thermoplastic polymer, and optionally an emulsion stabilizer;
wherein the nucleating agent comprises a salt of benzoic acid, and the salt of benzoic acid comprises lithium benzoate, sodium benzoate, aluminum benzoate, potassium benzoate, or any combination thereof;

shearing the mixture at a temperature at or greater than a melting point or softening temperature of the thermoplastic polymer to emulsify a thermoplastic polymer melt in the carrier fluid;
cooling the mixture to below the melting point or softening temperature to form polymer particles comprising the thermoplastic polymer and the nucleating agent; and
separating the polymer particles from the carrier fluid, wherein the polymer particles separated from the carrier fluid comprise the thermoplastic polymer and the nucleating agent and have a crystallization temperature that is substantially the same as a crystallization temperature of the thermoplastic polymer.
