Process for the production of brominated chlorine-substituted poly-1,3-butadiene

摘要

Brominated chlorine-substituted poly-1,3-butadiene is produced by a process in which an aqueous chlorine-substituted poly-1,3-butadiene latex is reacted in aqueous phase with a brominating agent in the presence of a radical-forming catalyst and/or in the presence of light at a pH value below 7 and at a temperature of 20 degrees to 95 degrees C., the brominated reaction product is optionally precipitated from the aqueous dispersion obtained and then separated from the aqueous liquid.
