Kinetics of the reactions of the acid anhydrides with aromatic amines in aprotic solvents [PDF]
Work has revealed that diamine derivatives of diphenylmethane (IV), diphenyl ether (V), benzophenone (IV), fluorene (VII), and fluorenone (VIII) polymerizations with pyromellitic dianhydride in DMA were dependent on the basicity of the amine compound ...
