ABSTRACT:
A composition for a cross-linkable hot melt adhesive is provided and is formed by an ethylene-vinyl acetate copolymer containing primary hydroxyl functions and a blocked polyisocyanate. This composition when associated with a tackifying resin which can also serve as blocking agent of the polyisocyanate, is a cross-linkable hot melt adhesive. The adhesive is used at a temperature at least equal to splitting temperature of the isocyanate functions of the polyisocyanate. The temperature at which such adhesives retain adherence can reach about 200.degree.-220.degree. C.
