1. A process of forming a flame retardant polycaprolactone, the process comprising:

  • utilizing a caprolactone molecule to form a hydroxyl-functionalized caprolactone molecule;

    chemically reacting the hydroxyl-functionalized caprolactone molecule with a phosphorus-containing flame retardant molecule to form a flame retardant-functionalized caprolactone monomer; and

    polymerizing a mixture that includes at least the flame retardant-functionalized caprolactone monomer to form a flame retardant polycaprolactone.
