Abstract: In this paper, we studied the protonation of poly(N,N-dimethylaniline) (PDMA)in two different acid media (sulfuric acid and trichloroacetic acid). Using UV-Vis and 1H NMR measurements, we found that PDMA could present two types of protonated states,which depends on the acidity. It can be concluded that protons were added on nitrogen atoms of substituent in the concentrated acid but on benzene ring of main chain in the moderate acid solution.
Key words: Poly (N, N-dimethylaniline), Acid media, Protonated states
