Synthesis, characterization and desalination study of novel PSAB and MPSAB blend membranes with polysulfone (PSF)
The present paper describes the synthesis of poly sulphonyl amino benzamide (PSAB) and methyalated poly sulphonyl amino benzamide (mPSAB) polymer, using terephthalic acid chloride and substituted 4-amino-1-benzensulphonmide in N-methyl-2-pyrrolidone. Polymers were characterized by FT-IR, NMR and GPC...
