Title: Thermal decomposition studies of cotton radiolytically grafted with phosphours- and bormine-containing flame retardants

Thermal analysis of cotton samples grafted with traillylphosphate (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/sub 3/PO/sub 4/ formed during the decomposition of the grafted poly-TAP. The HBr evolved during decomposition was monitored conitnuously during thermal analysis of cotton grafted with ploly-TBEA. No significant flame-retarding effect by HBr was found. Since grafred 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 phasse before most of te HBr is released.
