Process for brominating butadiene polymers using mixed solvents
Butadiene polymers are brominated using a quaternary ammonium or quaternary phosphonium tribromide as the brominating agent. The bromination is performed in a solvent mixture than contains at least one polyhalogenated alkane and at least one monohalogenated alkane. The process proceeds easily under mild conditions and allows high conversions to be achieved easily.
