A carboxymethyl derivative of scleroglucan (Scl-CM) was synthesized and characterized through FT-IR, 1 H NMR and potentiometer titration. Rheological studies allowed evidencing the effect produced by the introduction of the carboxymethyl moiety on the native polymer. The mechanical spectrum of the scleroglucan solution showed a weak gel behaviour, while the derivative one looked like a system...
