As a high-performance polymer, biphenyl polyimide has heat resistance, solvent resistance, radiation resistance and good mechanical and dielectric properties. It is used in mechatronics, aerospace, large motors, turbine bearings, heat-resistant filters It has broad application prospects in the fields of materials and so on.
Compared with the polyimide with the symmetric structure of 3,3',4,4'-biphenyltetracarboxylic dianhydride (4,4'-BPDA) as the monomer, the asymmetric structure isomers 2,3,3 ',4'-Biphenyltetracarboxylic dianhydride (3,4'-BPDA) as the monomer of polyimide has higher Tg and lower melt viscosity, which significantly improves the processability during material preparation.
