Optical absorber-containing thermoplastic polymer particles (OACTP particles) may be produced by methods that comprise: mixing a mixture comprising a thermoplastic polymer, a carrier fluid that is immiscible with the thermoplastic polymer, and optionally an emulsion stabilizer at a temperature greater than a melting point or softening temperature of the thermoplastic polymer and at a shear rate sufficiently high to disperse the thermoplastic polymer in the carrier fluid; cooling the mixture to below the melting point or softening temperature of the thermoplastic polymer to form solidified particles comprising the thermoplastic polymer; separating the solidified particles from the carrier fluid; and exposing the solidified particles to an optical absorber to produce the OACTP particles.
含光吸收剂的热塑性聚合物颗粒(OACTP 颗粒)的生产方法包括在高于热塑性聚合物熔点或软化温度的温度下,并以足够高的剪切速率将热塑性聚合物分散在载液中,混合包含热塑性聚合物、与热塑性聚合物不相溶的载液以及乳液稳定剂的混合物;将混合物冷却至低于热塑性聚合物熔点或软化温度,以形成包含热塑性聚合物的固化颗粒;将固化颗粒与载液分离;以及将固化颗粒暴露于光学吸收剂,以产生 OACTP 颗粒。
