Derivatives of cellulose, amylose and chitosan, bearing simultaneously 10-undecenoyl and arylaminocarbonyl or benzoyl groups were characterized by the combined use of 1H NMR and elemental analysis. The mathematical manipulation of elemental analysis data permits the calculation of the degree of substitution for each kind of substituent. The method was validated and is applicable to other derivatives.
