Abstract
Flameproofing composition comprises an O,O,O-triester of phosphorus, phosphoric or thiophosphoric acid and a haloalkyl aryl ether, and optionally a chlorinated aliphatic hydrocarbon and/or an organic tin or lead compound. The composition is useful for flameproofing polymeric organic materials, especially synthetic polymeric organic materials such as polypropylene, which may alternatively be flameproofed by treatment separately with the individual components of the composition.
