    • The present invention provides a method for preparing relatively insoluble bisimides under conditions which afford high imidization reaction rates and which permit the monitoring and adjustment of reactant stoichiometry at any stage of the reaction. The bisimides provided by the present invention are prepared either by reaction of a diamine such as 4,4′-diaminodiphenylsulfone (DDS) with an anhydride, for example 3-chlorophthalic anhydride (3-ClPA) in the presence of a solvent at a pressure greater than one atmosphere and at a temperature above the normal boiling point of the solvent, or by reaction of a monoamine with a dianhydride under the same conditions. In one embodiment, the relatively insoluble product bisimides provided by the present invention have a solubility in ortho-dichlorobenzene of less than about 10 percent by weight at a temperature of about 180° C.
    • 本发明提供了在提供高酰亚胺化反应速率并允许在反应的任何阶段监测和调节反应物化学计量的条件下制备相对不溶性双酰亚胺的方法。 本发明提供的双酰亚胺通过在溶剂存在下,在压力存在下,通过使诸如4,4'-二氨基二苯基砜(DDS)的二胺与酸酐例如3-氯邻苯二甲酸酐(3-ClPA) 大于一个气氛,并且在高于溶剂的标准沸点的温度下,或在相同条件下通过单胺与二酐的反应。 在一个实施方案中,本发明提供的相对不溶性产物双酰亚胺在约180℃的温度下在邻二氯苯中的溶解度小于约10重量%
