Benzophenone-3,3′,4,4′-tetracarboxylic acid is formed by hydrolysis, it can be converted to the dianhydride by treating with Ac2O (molar ratio 4 to 1 of acid).The dianhydride is used to synthesize polyimides, which are highly flexible in nature due to the presence of keto and carbonyl groups in the dianhydride molecule. The keto and carbonyl groups subsequently increase the spacing between the imide rings enhancing the solubility and processibility.
