ABSTRACT OF THE DISCLOSURE The softening temperature or heat resistance of a hot melt composition containing an ethylene-vinyl acetate copolymer and/or rubber is improved by blending an oxidized low molecular weight propylene-ethylene copolymer having a molecular weight of 500 - 10,000, an acid value of 1 - 20 and an ethylene content of 1 - 20 weight % with the ethylene-vinyl acetate copolymer and/ or rubber in a weight ratio of 1/100 - 60/10 relative to the weight of ethylene-vinyl acetate copolymer and/or rubber. The ethylene-vinyl acetate copolymer has a vinyl acetate content of 10 - 45 weight percent and a melt index of 1 - 1,000 g/10 min., the rubber having a mooney viscosity at 25-C of 1 - 20. The composition also includes at least one additive selected from the group consisting of a tackifier, wax and asphalt.
