    • A method for manufacturing a poly(imide) prepolymer powder includes combining a bisanhydride powder or organic diamine and a solvent comprising an alcohol, a water-soluble ketone or water to form a mixture, adding an organic diamine or bisanhydride powder to the mixture to form a poly(imide) prepolymer, and removing the solvent to provide the poly(imide) prepolymer powder. A method for manufacturing a poly(imide) prepolymer varnish includes combining a bisanhydride powder or organic diamine and a solvent comprising an alcohol, a water-soluble ketone or water to form a mixture, and adding an organic diamine or bisanhydride powder to the mixture to form a poly(imide) prepolymer. The method of manufacturing the varnish further includes at least one of adding an effective amount of a secondary or tertiary amine to solubilize the poly(imide) prepolymer powder, heating the mixture to a temperature effective to provide the varnish, or agitating the mixture to provide the varnish. The poly(imide) prepolymer powder and varnish can have a residual organic diamine content of less than or equal to 1000 ppm. A poly(imide) polymer prepared from the prepolymer powder or varnish is also disclosed.
    • 用于制造聚(酰亚胺)预聚物粉末的方法包括将二酸酐粉末或有机二胺与包含醇,水溶性酮或水的溶剂混合以形成混合物,将有机二胺 或二氢化铝粉末混合以形成聚(酰亚胺)预聚物,并除去溶剂以提供聚(酰亚胺)预聚物粉末。 制备聚酰亚胺预聚物清漆的方法包括将二酸酐粉末或有机二胺与包含醇,水溶性酮或水的溶剂混合以形成混合物,并将有机二胺或二酐粉末加入到混合物中 形成聚(酰亚胺)预聚物。 制造清漆的方法进一步包括添加有效量的仲或叔胺以溶解聚(酰亚胺)预聚物粉末,将混合物加热至有效提供清漆的温度或搅拌混合物以提供 清漆。 聚(酰亚胺)预聚物粉末和清漆可具有小于或等于1000ppm的残余有机二胺含量。 还公开了由预聚物粉末或清漆制备的聚(酰亚胺)聚合物。
