Abstract
Official abstract text for this publication.
A process a process of forming a non-halogenated flame retardant hindered amine light stabilizer (HALS) impact modifier is disclosed. The process includes forming a mixture of monomers that includes an acryloyl-functionalized 2,2,6,6-tetramethylpiperidine (TMP) monomer, a styrene monomer, a butadiene monomer, and a phosphorus-functionalized monomer. The process also includes initiating a polymerization reaction of the mixture of monomers to form a non-halogenated flame retardant HALS impact modifier.
First claim

What is claimed is: 1. A process of forming a non-halogenated flame retardant hindered amine light stabilizer (HALS) impact modifier, the process comprising: forming a mixture of monomers that includes an acryloyl-functionalized 2,2,6,6-tetramethylpiperidine (TMP) monomer, a styrene monomer, a butadiene monomer, and a phosphorus-functionalized styrenic monomer; and initiating a polymerization reaction of the mixture to form a non-halogenated flame retardant HALS impact modifier. 2. The process of claim 1 , further comprising converting a piperidine amide bridge of the non-halogenated flame retardant HALS impact modifier to a nitroxyl radical, the nitroxyl radical to be utilized to bond the non-halogenated flame retardant HALS impact modifier to a polymeric material to form an impact resistant, flame retardant, light-stabilized polymeric material. 3. The process of claim 1 , wherein the acryloyl-functionalized TMP monomer includes N-(2,2,6,6-tetramethylpiperidin-4-yl)methacrylamide. 4. The process of claim 1 , wherein the acryloyl-functionalized TMP monomer includes N-(2,2,6,6-tetramethylpiperidin-4-yl)acrylamide. 5. The process of claim 1 , wherein the acryloyl-functionalized TMP monomer includes 2,2,6,6-tetramethylpiperidin-4-yl methacrylate. 6. The process of claim 1 , wherein the acryloyl-functionalized TMP monomer includes 2,2,6,6-tetramethylpiperidin-4-yl acrylate. 7. A process of forming a non-halogenated flame retardant hindered amine light stabilizer (HALS) impact modifier, the process comprising: forming a mixture of monomers that includes an acryloyl-functionalized 2,2,6,6-tetramethylpiperidine (TMP) monomer, a styrene monomer, a butadiene monomer, and a phosphorus-functionalized monomer; and initiating a reversible addition-fragmentation chain transfer (RAFT) polymerization reaction of the mixture to form a non-halogenated flame retardant HALS impact modifier. 8. The process of claim 7 , further comprising converting a piperidine amide bridge of the non-halogenated flame retardant HALS impact modifier to a nitroxyl radical, the nitroxyl radical to be utilized to bond the non-halogenated flame retardant HALS impact modifier to a polymeric material to form an impact resistant, flame retardant, light-stabilized polymeric material. 9. The process of claim 7 , wherein the acryloyl-functionalized TMP monomer includes N-(2,2,6,6-tetramethylpiperidin-4-yl)methacrylamide. 10. The process of claim 7 , wherein the acryloyl-functionalized TMP monomer includes N-(2,2,6,6-tetramethylpiperidin-4-yl)acrylamide. 11. The process of claim 7 , wherein the acryloyl-functionalized TMP monomer includes 2,2,6,6-tetramethylpiperidin-4-yl methacrylate. 12. The process of claim 7 , wherein the acryloyl-functionalized TMP monomer includes 2,2,6,6-tetramethylpiperidin-4-yl acrylate. 13. The process of claim 7 , wherein the phosphorus-functionalized monomer includes a phosphorus-functionalized acrylate monomer or a phosphorus-functionalized styrenic monomer. 14. A process of forming a non-halogenated flame retardant hindered amine light stabilizer (HALS) impact modifier, the process comprising: forming a mixture of monomers that includes an acryloyl-functionalized 2,2,6,6-tetramethylpiperidine (TMP) monomer, a styrene monomer, a butadiene monomer, and a phosphorus-functionalized monomer; and initiating a radical polymerization reaction of the mixture to form a non-halogenated flame retardant HALS impact modifier, the radical polymerization reaction utilizing a photo-initiator. 15. The process of claim 14 , further comprising converting a piperidine amide bridge of the non-halogenated flame retardant HALS impact modifier to a nitroxyl radical, the nitroxyl radical to be utilized to bond the non-halogenated flame retardant HALS impact modifier to a polymeric material to form an impact resistant, flame retardant, light-stabilized polymeric material. 16. The process of claim 14 , wherein the acryloyl-functionalized TMP monomer includes N-(2,2,6,6-tetramethylpiperidin-4-yl)methacrylamide. 17. The process of claim 14 , wherein the acryloyl-functionalized TMP monomer includes N-(2,2,6,6-tetramethylpiperidin-4-yl)acrylamide. 18. The process of claim 14 , wherein the acryloyl-functionalized TMP monomer includes 2,2,6,6-tetramethylpiperidin-4-yl methacrylate. 19. The process of claim 14 , wherein the acryloyl-functionalized TMP monomer includes 2,2,6,6-tetramethylpiperidin-4-yl acrylate. 20. The process of claim 14 , wherein the phosphorus-functionalized monomer includes a phosphorus-functionalized acrylate monomer or a phosphorus-functionalized styrenic monomer.
