Collection: Tetracarboxylic Dianhydride Monomers

Tetracarboxylic Dianhydride Monomers — includes aromatic and alicyclic tetracarboxylic dianhydride compounds, monomers with four carboxylic groups that form a pair of anhydride rings on a single molecular framework. These compounds are one of the two main monomers that form polyimides through a condensation reaction with diamine compounds.

Tetracarboxylic Dianhydride Monomers are used by materials researchers and polymer engineers to synthesize polyamic acid, which is then imidized into heat-resistant and mechanically stable polyimide films or resins. The aromatic structure provides chain rigidity and a dark color in films, while alicyclic or fluorine-containing structures are used to obtain transparent and optically clear polyimides. This monomer is also used in the development of flexible electronic substrates and insulation materials.

Choose based on the core structure (aromatic, alicyclic, or containing fluorine groups) according to the optical and thermal properties desired for the polyimide, and pay attention to purity and water content, because anhydride groups are highly reactive toward moisture. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
