  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.
