| application | biphenyl polyimide is a high-performance polymer with heat resistance, solvent resistance, radiation resistance, good mechanical and dielectric properties, and has broad application prospects in the fields of mechanical electronics, aerospace, large motors, hydraulic turbine bearings, heat-resistant filter materials, etc. Compared with polyimide with symmetrical structure 3,3 ',4,4'-biphenyltetracarboxylic dianhydride (4,4 '-BPDA) as monomer, the asymmetric structure isomer 2,3,3,3',4 '-biphenyltetracarboxylic dianhydride (3,4'-BPDA) as monomer polyimide has higher Tg and lower melt viscosity, which significantly improves the processability in the material preparation process. Therefore, more and more attention has been paid to the use of 3,4 '-BPDA instead of 4,4'-BPDA matrix resin. |
