2,3,3’,4’-Tetracarboxydiphenyl Oxide Dianhydride CAS: 50662-95-8

2,3,3’,4’-Tetracarboxydiphenyl oxide dianhydride is the one of the new structural monomers developed to improve the rigidity of high performance engineering polymer materials-polyimide. The synthesis of Fusible polyimide with monoether anhydride, in addition to its superior thermal stability, heat resistance, oxidation, good mechanical properties and dielectric properties, has been reduced due to the introduction of flexible ether bonds in the polyimide main chain. Softening temperature, Therefore, the performance of resin forming has been significantly improved. It has a wide range of uses in defense and civilian industries. Monoanhydride ether is the most used monomer for the synthesis of polyimide.   2,3,3’,4’-Tetracarboxydiphenyl oxide dianhydride is also named as α-ODPA; 4-[(1,3-Dihydro-1,3-dioxo-5-isobenzofuranyl)oxy]-1,3-isobenzofurandione.
