The titular alicyclic tetracarboxylic dianhydrides were synthesized with endo- and/or exo-5-norbornene-2,3-dicarboxylic anhydride and 1,1,3,3,5,5-hexamethyltrisiloxane. The endo-structure ...

Researchers have now altered two-dimensional tetracarboxylic acid networks through only small chemical changes. This phase behaviour reveals that entropy, alongside energy, ...

Dianhydride curing agents, such as benzophenone tetracarboxylic dianhydride (BTDA ®), enhance high-temperature performance in epoxy formulations.. This article will examine sample formulations for ...

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 ...
