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

Dianhydrides like BTDA ® (benzophenone tetracarboxylic dianhydride) are important comonomers in the production of polyimide resins. This article will discuss these polyimides and their use in a ...
