A method for producing polyimide microparticles may comprise: combining a diamine and a dianhydride in a first dry, high boiling point solvent; reacting the diamine and the dianhydride to produce a mixture comprising poly(amic acid) (PAA) and the first dry, high boiling point solvent; emulsifying the mixture in a matrix fluid that is immiscible with the first dry, high boiling point solvent using an emulsion stabilizer to form a precursor emulsion that is an oil-in-oil emulsion; and heating the precursor emulsion during and/or after formation to a temperature sufficient to polymerize the PAA to form the polyimide microparticles.
生产聚
酰亚胺微粒的方法可包括在第一种干燥的高沸点溶剂中混合二胺和二酸酐;使二胺和二酸酐反应,生成包含聚(胺基酸)(P
AA)和第一种干燥的高沸点溶剂的混合物;使用乳液稳定剂将混合物乳化在与第一种干燥高沸点溶剂不相溶的基质流体中,以形成油包油型前驱乳液;以及 在形成过程中和/或形成后将前驱乳液加热到足以聚合 P
AA 的温度,以形成聚
酰亚胺微粒。
