THERMOGRAVIMETRIC STUDIES OF CHITOSAN DERIVATIVES
(ELSEVIER SCIENCE BV, 1992)
The thermal stabilities of chitosan derivatives (chito; 2-amino-2-deoxy(1-4)-beta-D-glucopyranan) have been studied by thermogravimetry (TG) between 25 and 550-degrees-C under nitrogen flow. The kinetic data thus obtained ...
