New silver nanocomposites based on polysulfones of 2,2-diallyl-1,1,3,3-tetraethylguanidiniumchloride [poly(AGC–SO2)], tris(diethylamino)diallylaminophosphonium tetrafluoroborate [poly(DAAP–BF4–SO2)] and chloride [poly(DAAP–Cl–SO2)] have been developed. UV-spectroscopy, SEM XRD techniques were used to characterize the formation nanoparticles in copolymers. Antibacterial action new S. epidermidis...
