description Flame retardant poly(alkenyl aromatic) oligomers and lower molecular weight polymers having bromine substituents on the aromatic nucleus are prepared by cationic polymerization from the corresponding brominated monomers, for example, bromostyrene, in an organic solvent, using a Lewis acid catalyst and an aromatic chain transfer agent. The lower molecular weights enable greater tolerance with other thermoplastic polymers, and as a result compatible flame retardant blends with good ductile impact properties are possible. Des oligomères de poly(alkényles aromatiques) retardateurs de la flamme et des polymères de poids moléculaire plus faible ayant des substituants du brome sur le noyau aromatique sont préparés par polymérisation cationique à partir des monomères bromés correspondants, par exemple du bromostyrène, dans un solvant organique, en utilisant un catalyseur d'acide de Lewis et un agent de transfert de chaîne aromatique. Les poids moléculaires plus faibles permettent une tolérance plus grande avec d'autres polymères thermoplastiques et il est possible d'obtenir des mélanges compatibles retardateurs de la flamme ayant de bonnes propriétés de ductilité et de résistance au choc.
