Abstract
A process for the bromination of a copolymer of an isoolefin having from 4 to 7 carbon atoms and a para-alkystyrene comprising bromating the copolymer in the presence of bromine and a radical initiator thereby providing a brominated copolymer of the copolymer. The brominated copolymer is substantially free of ring bromine and backbone bromine.
