The thermal behavior of polychlal fiber partially phosphorylated with phosphorus oxychloride has been studied using a conventional dynamic thermogravimetric technique. The dynamic thermogravimetric analysis curves have been analyzed using analytical methods reported in the literature to obtain information about the sequential stages in the thermal degradation process. The data obtained reveals that the phosphorus system is capable of modifying the degradation kinetics, with the phosphorylated polychlal fiber having a reduced maximum activation energy and more rapid weight loss dur ing the initial degradation.
