Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 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. 2. The process of claim 1 , wherein the mixture further includes an unfunctionalized caprolactone monomer, and wherein the flame retardant polycaprolactone includes a flame retardant polycaprolactone copolymer. 3. The process of claim 1 , wherein the phosphorus-containing flame retardant molecule includes a cross-linking moiety to cross-link the flame retardant polycaprolactone into a second polymeric material. 4. The process of claim 3 , wherein the cross-linking moiety includes an allyl group, an epoxide group, or a furan group. 5. The process of claim 3 , wherein the cross-linking moiety includes an allyl group, and wherein the phosphorus-containing flame retardant molecule is formed from allylic alcohol. 6. The process of claim 3 , wherein the cross-linking moiety includes an epoxide group, and wherein the phosphorus-containing flame retardant molecule is formed from glycidol. 7. The process of claim 3 , wherein the cross-linking moiety includes a furan group, and wherein the phosphorus-containing flame retardant molecule is formed from furfuryl alcohol. 8. The process of claim 3 , wherein the cross-linking moiety includes a furan group, and wherein the phosphorus-containing flame retardant molecule is formed from 2-(chloromethyl)furan. 9. 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 that includes an allyl group to form a flame retardant-functionalized caprolactone molecule that includes the allyl group; chemically reacting the allyl group of the flame retardant-functionalized caprolactone molecule with a thiol that includes a cross-linking moiety to form a flame retardant-functionalized caprolactone monomer that includes the cross-linking moiety; and polymerizing a mixture that includes at least the flame retardant-functionalized caprolactone monomer to form a flame retardant polycaprolactone. 10. The process of claim 9 , wherein the cross-linking moiety includes a hydroxyl group, an amine group, a carboxyl group, or an ester group to cross-link the flame retardant polycaprolactone into a second polymeric material. 11. The process of claim 10 , further comprising chemically reacting the flame retardant polycaprolactone and the second polymeric material to form a cross-linked flame retardant polymeric material. 12. The process of claim 9 , wherein the phosphorus-containing flame retardant molecule includes a phosphate molecule that includes the allyl group and a chloride group to chemically react with a hydroxyl group of the hydroxyl-functionalized caprolactone molecule. 13. The process of claim 9 , wherein the phosphorus-containing flame retardant molecule includes a phosphonate molecule that includes the allyl group and a chloride group to chemically react with a hydroxyl group of the hydroxyl-functionalized caprolactone molecule. 14. The process of claim 9 , wherein the mixture further includes an unfunctionalized caprolactone monomer, and wherein the flame retardant polycaprolactone includes a flame retardant polycaprolactone copolymer.
