Collection: Tetracarboxylic Dianhydrides [Polyimide Raw Materials]

Tetracarboxylic Dianhydrides [Polyimide Raw Materials] — This collection gathers tetracarboxylic dianhydride monomers, compounds with four carboxylic groups that form two anhydride rings, as the main raw materials for polyimide synthesis. The aromatic or alicyclic structure of these dianhydrides determines the thermal resistance and optical properties of the resulting polyimide films.

Tetracarboxylic Dianhydrides are used by polymer chemistry and electronic materials researchers to react with diamines and form polyamic acid, which is then imidized into heat-resistant polyimide films. Aromatic dianhydrides such as phthalate derivatives are used for dielectric film and flexible substrate applications, while alicyclic dianhydrides are chosen when high optical transparency is required, for example in research on colorless polyimide materials.

Example products in this collection: TCI I0856 38103-06-9 4,4'-(4,4'-Isopropylidenediphenoxy)diphthalic Anhydride, TCI B6198 2754-40-7 Bicyclo[2.2.2]octane-2,3,5,6-tetracarboxylic 2,3:5,6-Dianhydride, TCI T4007 223255-30-9 N,N'-[(Perfluoropropane-2,2-diyl)bis(6-hydroxy-3,1-phenylene)]bis(1,3-dioxo-1,3-dihydroisobenzofuran-5-carboxamide), TCI B6612 2770-50-5 Propane-2,2-diylbis(4,1-phenylene) Bis(1,3-dioxo-1,3-dihydroisobenzofuran-5-carboxylate), TCI T3871 632-79-1 Tetrabromophthalic Anhydride (purified by sublimation), TCI C0046 552-30-7 Trimellitic Anhydride, TCI T2698 738-90-9 Tricyclo[6.4.0.0(2,7)]dodecane-1,8:2,7-tetracarboxylic Dianhydride, TCI C0857 6053-68-5 1,2,3,4-Cyclopentanetetracarboxylic Dianhydride.

Pay attention to purity, water content, and the crystal or powder form of the dianhydride, because anhydride groups are easily hydrolyzed and strongly affect the molecular weight of the polyamic acid formed during polymerization. All products are authentic Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
