New sulfonated copolyimides with ether and oligo ethylene glycol sequence in back bone were synthesized
by reaction of synthesized diamine 4,4'-bis(5-amino-1-naphtoxy)-benzhophenon-3,3΄-disulfonic acid(BANBPDS) in
companion with two nonsulfonated diamines 4,4΄-oxydianiline (ODA) and 1,8-diamino-3,6-dioxaoctane (DADO) and
reaction with 1,4,5,8-naphtalene tetracarboxylic dianhydride (NTDA). After characterization of the monomers and
polymers with common methods the sulfonated polyimides were characterized for their viscosity, molecular weight,
processability, solubility, and thermal stability. All the sulfonated polyimides had good thermal stability and exhibited a
three-step degradation pattern while have good processability and solubility.
