Abstract
A biobased flame retardant, a process for forming a biobased flame retardant, and an article of manufacture. The flame-retardant compound includes at least one moiety derived from a biobased dicarboxylic acid and at least one organophosphorus moiety. The process includes providing an organophosphorus compound and malic acid or a hydroxylated derivative of a biobased dicarboxylic acid. The process also includes reacting the organophosphorus compound and the malic acid or hydroxylated derivative to form a flame retardant. The article of manufacture includes a polymer and an organophosphorus flame retardant derived from a biobased dicarboxylic acid.
