Abstract: A flame-retardant aconitic acid-derived monomer, a process for forming a flame-retardant polymer, and an article of manufacture comprising a material that contains a flame-retardant aconitic acid-derived monomer are disclosed. The flame-retardant aconitic acid-derived monomer can have at least one phosphoryl or phosphonyl moiety with functional groups that can participate in a polymerization reaction, such as allyl, epoxy, or propylene carbonate functional groups. The process for forming the flame-retardant polymer can include forming an aconitic acid derivative, forming a phosphorus-based flame-retardant molecule, and reacting the aconitic acid derivative with the phosphorus-based flame-retardant molecule to form a flame-retardant aconitic acid-derived monomer, which is then polymerized. The aconitic acid derivative can be synthesized from aconitic acid obtained from a bio-based source. The material in the article of manufacture can be a resin or adhesive, and the article of manufacture can further comprise an electronic component.

Abstract: A flame retardant compound is provided. The flame retardant compound includes a polymer base resin, a carbonific host compound, and a guest compound including at least one atom of a transition metal. The carbonific host compound and the guest compound form a host-guest complex, and the host-guest complex acts to inhibit at least one of smoke release and smoke formation when exposed to heat. The host-guest complex is distributed within the polymer base resin. An intumescent flame retardant compound is also provided. The intumescent flame retardant compound includes a base resin, an acid donor, a spumific agent, a cyclodextrin host compound, and a guest compound including at least one atom of molybdenum. The cyclodextrin host compound and the guest compound form a host-guest complex. The acid donor, carbonific host compound, and spumific agent react when exposed to a temperature above 280° C. to form a foam.
