Abstract
Official abstract text for this publication.
A process a process of forming a non-halogenated flame retardant (FR) hindered amine light stabilizer (HALS) cross-linker is disclosed. The process includes forming a mixture that includes a first molecule having a hindered amine group. The first molecule corresponds to a functionalized 2,2,6,6-tetramethylpiperidine (TMP) molecule. The process also includes forming the non-halogenated FR HALS cross-linker via a chemical reaction of the first molecule a second molecule. The second molecule includes a phosphoryl group, a chloride group, and at least one cross-linkable (CL) moiety.
First claim
Opening claim text (preview).
What is claimed is: 1. A process of forming a non-halogenated flame retardant (FR) hindered amine light stabilizer (HALS) cross-linker, the process comprising: forming a mixture that includes a first molecule having a hindered amine group, the first molecule corresponding to a functionalized 2,2,6,6-tetramethylpiperidine (TMP) molecule having the following formula: wherein X corresponds to a hydroxyl (OH) group and wherein Z corresponds to a hydroxyl (OH) group; and forming a non-halogenated flame retardant (FR) hindered amine light stabilizer (HALS) cross-linker via a chemical reaction of the first molecule having the hindered amine group and a second molecule, the second molecule having the following formula: wherein CL is a cross-linker selected from a group consisting of an allyl functional group, a furan functional group, an epoxide functional group, a carbonate functional group, and an imide functional group.
