This invention provides intumescent, halogen-free, polymeric, silicon-phosphorus- nitrogen (SPN) flame retardant, a process for their preparation, and systems, compositions and articles into which they are incorporated. The inventive intumescent, halogen-free, SPN polymer compositions afford good flame retardant performance at a lower loading compared to conventional phosphorus and nitrogen based intumescent flame retardant compositions. La présente invention concerne un ignifuge polymère intumescent à base de silicium-phosphore-azote (SPN) sans halogène, son procédé de préparation et des systèmes, des compositions et des articles dans lesquels il est incorporé. Les compositions polymères intumescentes à base de SPN sans halogène selon l'invention présentent une bonne action ignifugeante à une charge moindre par rapport aux compositions classiques contenant un ignifuge intumescent à base de phosphore et d'azote.
