synthesis and characterization of novel blended poly (sulfide sulfone)/poly (ether sulfone) for membrane application

In this research, a novel aromatic poly (sulfide sulfone) (ppy) containing pyridine and sulfide groups was synthesized by polycondensation reactions of a new diol(diol-py) with bis(4-fluorophenyl) sulfone. also a poly (ether sulfone) (pbm) was prepared through reaction of 4,4′-(1,3-phenylenediisopropylidene) bisphenol(bisphenol m) with bis(4-fluorophenyl) sulfone similarly. the chemical structure of diol-py and polymers was identified by spectroscopic techniques like 1h-nmr and ft-ir. pbm/ppy blending samples with composition of 100/0, 75/25 and 50/50 wt% were prepared and specified by water contact angle, water absorption, tga, dsc, and tensile strength. according to dsc results, good miscibility of two polymers was concluded. thermal stability of pbm/ppy blend samples enhanced compared with pbm pure. water contact angle and water absorption evaluation indicated that the hydrophilicity of pbm improved by incorporating of ppy in the polymer solution.
