ABSTRACT:
This invention features a process for brominating styrenic polymers, which process comprises forming a reaction mass by feeding a mixture, (i) which is substantially free of a bromination catalyst and (ii) which is formed from at least brominating agent and a styrenic polymer, to a catalytic quantity of a bromination catalyst.
