Aromatic polysulfones for flame retardancy

A poly(ether sulfone) and a copoly(ester sulfone) were synthesized and characterized using elemental analyses, IR, 1H-NMR spectrometry, GPC, thermogravimetric analyses. These polysulfones which show good thermal stability and flame retardancy were applied on textile materials and measurements for the evaluation of the flame retardant effect were carried out.
