Claim 16:
17. 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 is 1,3:2,4-bis-O-(3,4-dimethylbenzylidene)-D-sorbitol, sodium 2,4,8,10-tetra-tert-butyl-12H-dibenzo[d,g][1,3,2]dioxaphosphocin-6-olate-6-oxide, bicyclo[2.2.1]heptane-2,3-dicarboxylic acid disodium salt, 2,2′-methylene-bis-(4,6-di-tert-butylphenyl) phosphate, 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.
