1. A process of preparing a flame retardant composition, the process comprising:
mixing an organic polymer component and an amount of a silyl functional component sufficient to impart a flame retardant property to the flame retardant composition, the organic polymer component including one or more of a thermoplastic polymer and a thermoset polymer, and the silyl functional component including a compound comprising a N—O—Si bond.
