Abstract

Disclosed are a preparation method of a phosphorus-nitrogen-silicon-containing polymeric flame retardant and application thereof. The chemical structure of the polymeric flame retardant is wherein m=10˜100, n=10˜100. The synergistic flame-retardant effect between the phosphorus, nitrogen, and silicon in the phosphorus-nitrogen-silicon-containing polymeric flame retardant increases the flame retardancy of epoxy resin.
