  • Abstract

    Four compounds of haloorganophosphonates(III), namely; (CH3)4N[C2H5PCl2Br] (I), (CH3)4N[C6H5PCl2Br] (II), (CH3)4N[C6H5PCl3] (III) and (CH3)4N[C6H5PBr3] (IV) were prepared and characterized by FTIR spectroscopy, CHN analysis and conductive measurements .These compounds were used as flame retardants for epoxy and unsaturated polyester resins in the percentages of (1, 3, 5 and 7%) according to three standard methods (ASTM). All of these compounds were effectively reduced the flammability and combustion of the resins. Additive IV was the most active one
