To derive the above-mentioned polyimides, many alicyclic tetracarboxylic dianhydrides have been synthesized with hydroesterification of unsaturated alicyclic compounds, oxidation of fused ...

These polymers have superior dielectric properties, provide thermal stability and resilience, and are resistant to many solvents and chemicals. Dianhydrides like BTDA ® (benzophenone tetracarboxylic ...
