Title: Flame retardants for natural and synthetic materials

Abstract: A process for rendering natural and synthetic materials and blends of the same flame retardant which entails treating the same with an aqueous dispersion of the flame retardant agent reduced to a finely divided state suspended in a latex medium and applied to the material with a finely divided metal oxide as synergist, by any convenient means; dried and set in place by baking. The active flame retardant agents are chlorinated cyclopentadieno compounds, chlorobrominated cyclopentadieno compounds, applied alone or in admixture with each other, or in admixture with brominated cyclopentadieno compounds, and in admixture with metallic oxides. The active flame retardant agents are reduced to a fine state of subdivision, preferably under 2 microns average particle diameter.
