20 Claims

1. An aqueous flame retardant dispersion comprising

water;

a brominated flame retardant which has an average particle size of about 20 μm or less, wherein the brominated flame retardant contains aromatically-bound bromine and is selected from a) brominated styrenic polymers which have weight average molecular weights of about 650 to about 950,000 and a bromine content of about 60 wt % or more, and/or b) a brominated anionic chain transfer vinyl aromatic polymer which contains about 70 wt % or more bromine;

at least one dispersant;

at least one wetting agent; and

at least one thickener;

wherein the flame retardant dispersion contains about 25 wt % or more brominated flame retardant, based on the total weight of the dispersion.
