Procedure

Next, the NMP solution (θ) of di-n-butyl pyromellitate was added to the NMP solution (η) of di-n-butyl 3,3′,4,4′-diphenylether-tetracarboxylate, and the flask containing them was cooled to 0° C., to which was dropwise added 20.56 g (0.173 mols) of thionyl chloride, and reacted therewith for 1 hour to obtain a mixed solution (ι) of di-n-butyl 3,3′,4,4′-diphenylether-tetracarboxylate dichloride and di-n-butyl pyromellitate dichloride.
