Thermal and spectroscopic studies on cellulose and its organophosphorus derivatives

Abstract

The thermal behaviour of cellulose and its organophosphorus derivatives in air has been studied by DTA. TO and DTG techniques from ambient temperature to 700·C. From the resulting data the energies of activation and the frequency factors were calculated for various stages of thermal degradation. The IR and EPR spectra of the chars were used in elucidating the flame retardancy mechanism for the thermal degradation of cellulose-6-(1 - pyrrolidinyl) phosphate (CPP).
