Abstract: DTA studies were made on cellulose treated with THPC and thiourea in the presence of trace amounts of ammonium dihydrogen orthophosphate as a function of hydrogen ion concentration in air and nitrogen atmospheres. The thermo grams showed differences in the decomposition temperatures, depending upon the pH of the formulations. The thermograms of the treated cellulose had sharp and well defined peaks in air atmosphere, whereas in nitrogen atmosphere, double peak patterns were observed. Infrared spectra of some selected samples, which had been partially or completely charred near the peak temperatures, gave an indication of dehydration and skeletal rearrangement of the thioamide linkage in the adduct.
