    摘要: The present invention relates to a hot-melt adhesive composition comprising: 20 to 80% of a blend comprising: 50 to 100% of (A), which denotes a polyamide-block graft copolymer consisting of a polyolefin backbone and at least one polyamide graft, 0 to 50% of at least one polymer (B) chosen from polyolefins and polyamides; 80 to 20% of a blend comprising at least one tackifying resin and optionally at least one product chosen from waxes, plasticizers and mineral fillers; in which: the said graft is attached to the backbone via the residues of an unsaturated monomer (X) chosen from unsaturated carboxylic acids, anhydrides of unsaturated carboxylic acids and unsaturated epoxides; the residues of the unsaturated monomer (X) are attached to the backbone by grafting or copolymerization from its double bond; the molar mass {overscore (M)}n of the grafts is between 1000 and 5000; the melting point of the grafts is between 100 and 190° C.; and the MFI of (A) is between 1 and 500 (g/10 mm at 190° C. under a load of 2.16 kg).

    摘要: The invention relates to a process for packaging reactive hot-melt adhesive, which consists of pouring the adhesive composition in the molten state directly into a container (1) coated with a material (2) which is abherent on its inner face and with a material (3) which is moistureproof on its outer face, the container being provided with at least one easy-opening start device; and in securing a moisture-proof lid (4) to the free face of the container. It also relates to the packaged adhesives.
