Abstract
A polybrominated flame-retardant compound, a process for forming a flame-retardant material, and an article of manufacture are disclosed. The polybrominated flame-retardant compound includes a cyclododecane moiety, at least two bromo groups, and at least one substituent having a reactive functional group. The process includes forming a polybromocyclododecane (PBCD) compound having at least one reactive functional group and incorporating the PBCD compound into a polymer in a process that includes covalent binding of the PBCD compound. The article of manufacture includes a flame-retardant material that comprises a polymer with a covalently-bound PBCD compound.
