PROBLEM TO BE SOLVED: To provide an economical and safe process for production of a high quality brominated polymers (for example, a brominated polystyrene resin) of a vinyl aromatic monomer. SOLUTION: The process for bromination of the vinyl aromatic monomer contains supply of a first flow containing a brominating agent, a second flow containing the vinyl aromatic polymer and a third flow containing a brominating catalyst in a reaction vessel.
