    Abstract: The compositions of the present invention comprise at least one substantially random interpolymer (or blends with other thermoplastics), one or more flame retardant compounds and, optionally one or more flame-retardant synergists. For levels of flame retardants which yield a halogen content of about 0.05 to about 50 parts-per-hundred resin (phr), depending on whether the structure is foamed or not, which in turn result in LOI levels greater than or equal to about 23% oxygen, the compositions of the present invention unexpectedly still retain desirable mechanical properties such as compressive strength, toughness, and elasticity.
