Conductimetric and Tensiometric studies of acrylamide-co-4vinylpyridine (AM-4VP-9) copolymer in aqueous media

Bouras Brahim, Mansri Ali & Hocine Tayeb
A copolymer of acrylamide (AM) and 4-vinylpyridine (4VP) (POLY(AM-CO-4VP)) was synthesized by radical adiabatic copolymerization in aqueous solution. The synthesized copolymer was identified by 1H NMR, 13C NMR, UV-visible spectra and conductimetry. The molecular weights are obtained by GPC and viscosity. The conductimetry measurement showed that the copolymerisation methods caused a hydrolysed acrylamide function. On the order hand the variation of the surface tension of aqueous copolymer solutions with copolymer concentration revealed a surfactant behavior...
