Process for brominating butadiene copolymers by the addition of water or certain solvents
 
Gorman of Dow, Michigan,  brominatged butadiene copolymers are using certain quaternary ammonium tribromides as the brominating agent.  The bromination process proceeds easily under mild conditions, and produces a brominated product that has excellent thermal stability. A quaternary ammonium monobromide salt is produced as a reaction by-product.  A solvent for the monobromide salt is added to the reaction after 25-90% bromination of the aliphatic carbon-carbon double bonds.  This provides for significantly shorter reaction times while providing a product with few impurities.
