Application

3,4'-Biphthalic Anhydride, a white to almost white powder or crystal, serves as a critical component in the synthesis of high-performance polyimide materials. This compound, known chemically as 2,3,3',4'-biphenyl tetracarboxylic dianhydride or a-BPDA, boasts impressive characteristics including superior heat resistance, solvent resistance, and radiation resistance, alongside noteworthy mechanical and dielectric properties. It is particularly valuable in the development of asymmetric biphenyl-type polyimides through its reaction with polyamides derived from p-phenylenediamine (PDA) or 4,4'-oxydiphenylamine (ODA). These polyimides feature a notably bent chain structure compared to their semi-rigid counterparts, yet demonstrate remarkably high glass transition temperatures (Tg) when adequately annealed. The structural rigidness of a-BPDA imparts these polyimides with enhanced stability and performance across various industrial applications. Furthermore, when combined with cyclohexylamine, a diimide derivative can be produced that exhibits prolonged luminescence, underscoring its innovative potential in advanced material fields.
