Descrizione

3,3',4,4'-Benzophenonetetracarboxylic dianhydride (BPTA) is a reactive dianhydride that contains a hydroxyl group and is a nitrogen-containing compound. It has good transport properties and chemical stability. It can be used to synthesize polyimides with high resistance, color, and thermal expansion. BPTA is used as the starting material for the synthesis of diphenyl ethers. In addition, it can be used to produce polymers with good thermal stability by reacting it with diphenylmethane diisocyanate. The reaction mechanism of BPTA is similar to that of benzophenone tetracarboxylic acid (BPTCA).
