Abstract:
A process of forming a flame retardant polycaprolactone includes utilizing a caprolactone molecule to form a hydroxyl-functionalized caprolactone molecule. The process also includes chemically reacting the hydroxyl-functionalized caprolactone molecule with a phosphorus-containing flame retardant molecule to form a flame retardant-functionalized caprolactone monomer. The process further includes polymerizing a mixture that includes at least the flame retardant-functionalized caprolactone monomer to form a flame retardant polycaprolactone.
