Abstract: Water-swellable hot-melt adhesives based on a tackifying resin, a water-dispersible EVA wax, an ethylene/acrylic ester copolymer, a water-soluble homo- or co-polymer and a super absorber polymer powder having an average particle size of less than 80 &mgr;m display a clearly improved swelling behavior in comparison with the prior art. Furthermore, the swelling agent is significantly more homogeneously distributed in the matrix. Such hot-melt adhesives are suitable for ensuring longitudinal water impermeability in modern cable structures, as water-swellable jointing compounds in the building industry in the area of building conservation and restoration. Such hot-melt adhesives are further suitable for the manufacture of absorbent textile fabrics in the personal hygiene sector.

Abstract: The present invention relates to a process for preparing a digital versatile disc. The process of the present invention includes providing a hot melt adhesive containing at least one thermoplastic elastomer, at least one hydrocarbon resin, at least one poly-&agr;-olefin, and at least one polar wax, and providing at least two disc blanks. The hot melt adhesive is applied directly or indirectly to at least one of the blanks and the blanks are bonded together using the hot melt adhesive. The present invention also provides a digital versatile disc containing the hot melt adhesive.

Abstract: Thermoplastic compositions based on a water-insoluble component of one or more thermoplastic copolymers and one or more resins with a saponification number and a water-soluble or water-dispersible component and a water-swellable component from the class of superabsorbers are suitable as water-swellable hotmelt adhesives. Such water-swellable hotmelt adhesives are preferably used for the production of watertight constructions, more particularly for the production of longitudinally watertight cable constructions.

Abstract: Hotmelt adhesives with a melt viscosity of >100,000 mPas at 160° C. are suitable for bonding substrate halves in the production of digital versatile discs (DVDs) and afford major process-related advantages over known UV-curing adhesives. In their pigmented embodiment, they are able to combine the three functions of adhesive bonding, protecting the metallic reflection layer against corrosion and forming a covering background for a text/graphics layer.

Abstract: A thermoplastic hot-melt adhesive based on a polymer blend of polyolefins is disclosed. An oligomer of an alpha-olefin with at least eight carbon atoms in the monomer and a molecular weight of the oligomer of up to 5,000, as well as other known additives, are added to the known mixture of a substantially amorphous poly-alpha-olefin and of a substantially crystalline poly-alpha-olefin. The impact strength, the viscosity and the flexibility at low temperatures are above all improved in this manner. These hot-melt adhesives are therefore suitable above all for gluing non-polar plastics in the automobile and electric industry.
