Brominated styrene-based polymers having surprisingly good physical properties in combination with flame retardancy are prepared from terpolymers of dibromostyrene, styrene and butadiene. Polymerization compositions were determined by bromine contents (% Br) of the polymers by Schoeninger Combustion Method and {sup 1}H NMR integration. Weight losses (% loss) were measured at 20{degrees}C/min by Thermogravimetric Analysis (TGA). Molecular weights were measured by GPC based on a standard molecular weight (MW) of polystyrene (PS)> Flammability of the latex products when used in textile backcoatings was testing by Motor Vehicle Safety Standard 302 (MVSS-302) flammability test. As latexes were used as non-woven binders, flammability was tested by exposure to a 4 in high, 1950{degrees}F propane flame from a Fisher Burner. When latexes were employed for carpet backing, flammability was tested by DOC. FF-1-70 (pill test) flammability tests.
