Abstract
A flame-retardant compound, a process for forming a flame-retardant polymer, and an article of manufacture are disclosed. The flame-retardant compound includes at least one muconic acid moiety and at least one phosphorus-based moiety. The process for forming the flame-retardant polymer includes obtaining a muconic acid compound, obtaining a muconic acid compound, reacting the muconic acid compound with the phosphorus compound to form a flame-retardant compound, and incorporating the flame-retardant compound into a polymer. The article of manufacture comprises a material that contains a flame-retardant compound derived from muconic acid.
