摘要

COMPOSITIONS OF ALKYLENE-ALKYL ACRYLATE COPOLYMERS HAVING IMPROVED FLAME RETARDANT PROPERTIES SUMMARY OF THE INVENTION This invention relates to compositions, having improved flame retardant properties and reduced gas evolution on burning, which contain an alkylene-alkyl acrylate copolymer, a halogenated flame retardant additive and an oxide, carbonate, hydroxide or sulfate of magnesium or calcium in an amount of more than 20 and up to about 30 percent by weight. The compositions of the present invention are particularly useful as jacketing material about industrial control cables and telephone wires and cables and as insulation about electrical conductors.
