Abstract
Based on the raw material of 2,2-bis(3-nitrophenyl)hexafluoropropane,in the presence of FeCL3/C and hydrazine monohydrate,the polyimide monomer of 2,2-bis(3-aminophenyl)hexafluoropropane was obtained and further characterized.Then,base on 2,2-bis(3-aminophenyl)hexafluoropropane reacted with 6FDA in DMF to give polyimides by condensation polymerization.
