Flame-retardant polyolefin with improved weatherability, molded or extruded articles thereof, and methods of achieving a lightfast and flame retardant condition

摘要

A process for achieving a lightfast and flame retardant nature of a propylene-ethylene copolymer, which process comprises adding a combination of the flame retardant tris (2,3-dibromopropyl) isocyanurate and a hindered amine light stabilizer of the hydrocarbyloxyamine or hydroxyhydrocarbyloxyamine Class comprises a propylene-ethylene copolymer.
