反応手順
One proceeds in accordance with Example 1, where in place of 3,4-diaminobenzoic acid, 4,5-diaminophthalic acid is used, and in place of 3,3'-dihydroxy-4,4'-diaminobiphenyl, 4.4'- diaminobiphenyl is used. Via tetracarboxylic acid, or the corresponding acid chloride, as an intermediate stage, a copolymer with phenylquinoxaline units and o-carboxyamide groupings (-CO-NH-) is thereby obtained. When annealed to approximately 400° C., they cyclize into imide structures.
