Abstract:
A method of rendering a polymer flame resistant comprising compounding said polymer with a synergistic mixture comprising:(i) from about 0.6 to about 3 percent of a non-halogenated N-alkoxy hindered amine flame retardant compound; and (ii) at least about 0.06 percent of carbon black; wherein said percentages are based on weight percent of polymer plus said synergistic mixture, and wherein polymer plus synergistic mixture equals 100 percent, and wherein the polymer plus synergistic mixture displays a greater flame resistance than a composition consisting of an identical polymer and an identical percentage amount of an identical non-halogenated N-alkoxy hindered amine and further wherein said polymer is a polyolefin polymerized from at least one olefin having between 2 and 12 carbon atoms.
