CA 2265785

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.

La présente invention se rapporte à un procédé de bromuration de styrènes-polymères, lequel consiste à former une masse réactionnelle en ajoutant à une quantité catalytique d'un catalyseur de bromuration un mélange (i) sensiblement dépourvu de catalyseur de bromuration et (ii) formé d'au moins un agent de bromuration et d'un styrène-polymère.
