TCA

3-(Carboxymethyl)-1,2,4-cyclopentanetricarboxylic acid1, 4:2,3-dianhydride (TCA) is an alicyclic dianhydride, which is widely used as a raw material for polyimide resins or polyamic acid resins in the application of alignment films for liquid-crystal-display devices due to good solubility and thermal stability. Based on our own developed synthetic process, TCA can be obtained in high purity with low ion content.
