반응 단계
The benzophenonetetracarboxylic dianhydrides are readily available from commercial sources or synthesis. For instance, 3,3′,4,4′-benzophenonetetracarboxylic dianhydride (BTDA) is available from Aldrich Chemical Co., Inc. (1001 W. St. Paul Ave., Milwaukee, Wis. 53233). 2,2′-Dichloro-4,4′,5,5′-benzophenone tetracarboxylic dianhydride is available from 4-chloro-o-xylene by Friedel-Crafts acylation with oxalyl chloride to give 2,2′-dichloro-4,4′,5,5′,-tetramethylbenzophenone, followed by oxidation with nitric acid and dehydration of the resulting tetracarboxylic acid as described by Falcigno, et al., J. Poly. Sci. 1992, 30, 1433.
