Summary:A polymeric composition includes a silane functionalized polyolefin, a brominated flame retardant having a Temperature of 5% Mass Loss from 300°C to 700°C as measured according to Thermogravimetric Analysis, wherein the brominated flame retardant is polymeric and has a weight average molecular weight of from 1,000 g/mol to 30,000 g/mol as measured using Gel Permeation Chromatography, and antimony trioxide. The polymeric composition has an antimony (Sb) to bromine (Br) molar ratio (Sb:Br molar ratio) of 0.35 to 0.98. L'invention concerne une composition polymère comprenant une polyoléfine fonctionnalisée par silane, un ignifugeant bromé dont la température correspondant à 5 % de perte de masse est comprise entre 300 °C et 700 °C, mesurée selon une analyse thermogravimétrique, l'ignifugeant bromé étant polymère et présentant un poids moléculaire moyen en poids compris entre 1000 g/mol et 30000 g/mol, mesuré au moyen d'une chromatographie par perméation de gel, et un trioxyde d'antimoine. La composition polymère présente un rapport molaire antimoine (Sb)/brome (Br) (rapport molaire Sb/Br) compris entre 0,35 et 0,98.
