Abstract
A process for forming a flame retardant polymer, as well as the flame retardant polymer, are disclosed. A flame retardant polymer is a polymer that can be resistant to thermal degradation and/or thermal oxidation. A flame retardant polymer can be mixed or otherwise incorporated into a standard polymer to give flame retardancy to the standard polymer. The flame retardant polymers can include polycaprolactone functionalized with flame retardant substituents. The flame retardant substituents can include halides, substituted phosphoryl, and substituted phosphonyl.
Claims6
A process of forming a flame retardant polycaprolactone, the process comprising:
- hydroxylating caprolactone;
- chemically reacting the hydroxylated caprolactone with a phosphorus-based compound to form a caprolactone monomer having phosphorus-based moieties;
- and
- polymerizing a mixture that includes at least the caprolactone monomer to form the flame retardant polycaprolactone.
