中文摘要the synthesis of mellophanic dianhydride (mpda), an isomer of pyromellitic dianhydride (pmda), was studied. a trend of forming cyclic oligomers in the reactions of mpda with 4,4'-oxydianiline (oda) or 4,4'-methylenedianiline (mda) in dmac was found. the cyclic dimer from mpda/mda was isolated and fully characterized, including an x-ray crystallographic analysis. the reactions of mpda with aromatic diamines were found much more complicated than those of pmda. a model study was performed to clarify the reactions. several byproducts were isolated and characterized, so that, in an usual two-step process to prepare polyimides, imide, amide linkage, and carboxylic group may be involved in the polymer structure. the water, either existing in solvent or being generated during the imidization, is the main reason for the side reactions. the properties of some polyimides derived from mpda and diamines were tested and compared with those of the isomeric polyimides derived from pmda.
