US 10,329,488 B2 · Lysine and proline based flame retardants

Abstract

A flame retardant lysine-based derivative, a process for forming a flame retardant lysine-based derivative, and an article of manufacture comprising a flame retardant lysine-based derivative are disclosed. The flame retardant lysine-derived molecule can be synthesized from a bio-based source, and can have at least one phosphoryl or phosphonyl moiety. A flame retardant proline-based derivative, a process for forming a flame retardant proline-based derivative, and an article of manufacture comprising a flame retardant proline-based derivative are also disclosed. The flame retardant proline-derived molecule can be synthesized from a bio-based source and can have at least one phosphoryl or phosphonyl moiety.
