Abstract

Certain ethylene copolymers that contain an ethylene/anhydride graft copolymer and a magnesium hydroxide or aluminum trihydrate flame and smoke retardant have a good balance of strength and flame and smoke retardant properties. The compositions preferably also contain polyethylene, and/or ionomeric ethylene copolymer and/or an ethylene/propylene elastomer.
