  • Hot melt adhesive compositions
    Patent number: 4460728
    Abstract: Hot melt adhesive compositions are prepared from ethylene copolymers, atactic polypropylene, tackifying resins and optional additives. The adhesives are non-pressure sensitive and are characterized by high cohesive strength, strong tack, and good heat, creep and cold resistance. In accordance with the preferred embodiment, the adhesives are formulated so as to be particularly adaptable for use in the construction of disposable diapers of the multi-line construction variety.
