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.

An electrically insulated conductor comprising an electrically conductive element surrounded by ultramicrocellular foamed polymer insulation having a void volume greater than about 75%, wherein the transmission speed of the insulated conductor is greater than 90% of the speed of light. Such insulated conductors are useful in computer and telecommunications applications.

A composition comprising 2-3 wt. % carbon black, 25-1000 ppm and preferably 75-250 ppm of a fluoroelastomer and the remainder polyethylene is disclosed. The fluoroelastomer prevents die buildup during extrusion of the composition which is believed to be caused by moisture associated with the carbon black. Alternatively, the die may be conditioned by extruding polyethylene containing 0. 5-5 wt. % of the fluoroelastomer and then carbon black containing polyethylene without the fluoroelastomer can be extruded for a substantial period before die buildup begins to occur.

The present invention relates generally to multi-layer film compositions which can be thermoformed and heat set into clear, transparent articles, having excellent barrier properties. The compositions comprise at least one barrier layer and at least one polyester layer, whereby the polyester layer will quickly crystallize and heat set into an optically clear layer material.
