Thermal analysis of cotton samples grafted with triallylphosphate (TAP) and 2,2,2‐tribromoethyl acrylate (TBEA) was carried out. Grafting of poly‐TAP causes a significant decrease in the decomposition temperature of cotton. The cotton decomposition is acid catalyzed by H 3 PO 4 formed during the decomposition of the grafted poly‐TAP. The HBr evolved during decomposition was monitored continuously during thermal analysis of cotton grafted with poly‐TBEA. No significant flame‐retarding effect by HBr was found. Since grafted poly‐TBEA causes a decrease in the decomposition temperature of cotton, it is suggested that the flame retardant mechanism for poly‐TBEA in cotton occurs mainly in the solid phase before most of the HBr is released.
