High field NMR characterization of carboxymethyl scleroglucan (Scl-CM) recently synthesized through reaction of the native polymer (Scl) with chloroacetic acid in basic conditions is discussed, reporting the position of the carboxymethyl groups in the scleroglucan moiety. The comparison between the Scl-CM and the Scl structures can be useful to comprehend their different profiles in the viscosity-shear rate curves and their different ability to form physical gels.

Abstract
High field NMR characterization of carboxymethyl scleroglucan (Scl-CM) recently synthesized through reaction of the native polymer (Scl) with chloroacetic acid in basic conditions is discussed, reporting the position of the carboxymethyl groups in the scleroglucan moiety. The comparison between the Scl-CM and the Scl structures can be useful to comprehend their different profiles in the viscosity-shear rate curves and their different ability to form physical gels.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
