Carboxymethyl cellulose derivatives bearing tetrabutylammonium moieties (CMC-TBA) were synthesized by the acidification of carboxymethyl cellulose (CMC) followed by acid-base neutralization with tetrabutylammonium hydroxide. The products were identified by Fourier transform infrared (FT-IR), 1H nuclear magnetic resonance (NMR) spectroscopy and the degrees of substitution (DS) values were also quantified according to the integral area values in 1H NMR spectra. It was revealed that DS values had a positive relationship with the molar ra
