A polyamine (PA) was prepared by condensation of 1,4-bischloromethyl benzene and 4,4'-diaminobiphenyl-3,3'-disulfonic acid. The PA was then treated with cyanuric chloride at 0_C followed by reaction with sulfanilic acid in THF in concentration. NaOH (PH 9-10) at room temperature for 8 h. The resultant polymer, designated as polyamine-s-triazine-sulfanilic acid (PATS), was characterized by elemental analysis, IR spectral studies, and thermogravimetry. The PATS sample was monitored for its ion-exchanging properties by batch equilibrium method.
