摘要：
A method for producing highly spherical polymer particles comprising a polyamide having an optical absorber in a backbone of the polyamide (IBOA-polyamide) may comprise: mixing a mixture comprising the IBOA-polyamide, a carrier fluid that is immiscible with the IBOA-polyamide, and optionally an emulsion stabilizer at a temperature greater than a melting point or softening temperature of the IBOA-polyamide and at a shear rate sufficiently high to disperse the IBOA-polyamide in the carrier fluid; and cooling the mixture to below the melting point or softening temperature of the IBOA-polyamide to form particles comprising the IBOA-polyamide and the emulsion stabilizer, when present, associated with an outer surface of the particles.
