Patent ID: 10287381

Abstract:
A process of forming a non-halogenated flame retardant hindered amine light stabilizer (HALS) impact modifier is disclosed. The process includes co-polymerizing 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 to form a co-polymer. The process also includes forming a non-halogenated flame retardant HALS impact modifier by converting a piperidine amide bridge of the co-polymer to a nitroxyl radical. The process further includes utilizing the nitroxyl radical to directly bond the non-halogenated flame retardant HALS impact modifier to a polymeric material to form an impact resistant, flame retardant, light-stabilized polymeric material.
