摘要:
A nonlimiting example method of forming polyamide polymer particles having pigments therein may comprising: mixing a mixture comprising a polyamide having a pigment pendent from a backbone of the polyamide (PP-polyamide), a carrier fluid that is immiscible with the PP-polyamide, and optionally an emulsion stabilizer at a temperature greater than a melting point or softening temperature of the PP-polyamide and at a shear rate sufficiently high to disperse the PP-polyamide in the carrier fluid; and cooling the mixture to below the melting point or softening temperature of the PP-polyamide to form solidified particles comprising the PP-polyamide and, when present, the emulsion stabilizer associated with an outer surface of the solidified particles. Said solidified particles may be used in additive manufacturing to make a variety of objects like containers, toys, furniture parts and decorative home goods, plastic gears, automotive parts, medical items, and the like.
