ABSTRACT Ethylene vinyl acetate polymer compositions, having surprisingly good physical properties in combination with flame retardancy, include graft copolymers represented by the formula: Image wherein n is > 1, EVA is ethylene vinyl acetate, and S is a grafted side chain having brominated monomeric units of the formula: Image wherein x = 1 to 4, R1 is H or CH3, and R2 is H or a C1-4 lower alkyl group. Polymer blends including such graft copolymers, and methods for making flame retardant polymer compositions, are also described.
