Abstract
A flame-retardant sugar derivative, a process for forming a flame-retardant sugar derivative, and an article of manufacture comprising a flame-retardant sugar derivative are disclosed. The flame-retardant sugar derivative can be synthesized from sorbitol, gluconic acid, or glucaric acid obtained from a bio-based source, and can have at least one phosphoryl or phosphonyl moiety. The process for forming the flame-retardant sugar derivative can include reacting sorbitol, gluconic acid, or glucaric acid and a flame-retardant phosphorus-based molecule to form the flame-retardant sugar derivative.
