Zusammenfassung: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.
