Abstract
Abstract The disclosure of this application is directed to compositions having improved flame retardant properties containing an alkylene-alkyl acrylate copolymer, a halogenated flame retardant additive and an oxide, carbonate, hydroxide or sulfate of magnesium or calcium in an amount more than 20 and up to about 30 percent by weight. The compositions disclosed are useful as jacketing material and as insulation about wire and cable.
