Abstract

L'invention concerne de nouveaux polymères styréniques bromés présentant une teneur en brome ionique inférieure ou égale à 2000ppm, et une ou plusieurs des caractéristiques suivantes: a) une température TGA supérieure ou égale à 340 ·C pour 1 % de perte pondérale, ainsi qu'une teneur en chlore inférieure ou égale, le cas échéant, à 700ppm Cl environ; b) un poids moléculaire (M¿w?) réel représentant approximativement 20 % du M¿w? théorique calculé, ce M¿w? théorique étant basé sur la teneur réelle en brome dudit polymère styrénique bromé et du M¿w? du réactif polymère styrénique utilisé pour produire ce polymère styrénique bromé; et c) sensiblement aucune teneur en impuretés choisies dans le groupe composé par le bichlorure d'éthylène, le bromodichloroéthane, le dibromochloroéthane, le dibromodichloroéthane, et le tribromochloroéthane. Ces polymères ignifuges présentent une performance améliorée en cours d'utilisation, en particulier lorsqu'ils sont employés dans des matières thermoplastiques comme les polyesters renforcés à la fibre de verre et le nylon renforcé à la fibre de verre.
