Abstract: Water-soluble or water-dispersible hotmelt adhesives are prepared using graft copolymers produced by graft copolymerizing olefinically unsaturated monomers onto polyalkylene oxides. The adhesives additionally contain at least one resin which improves tackiness and the compatibility of the adhesive components. Other components such as polymers, plasticizers, and additives may also be present. The adhesives are especially suited for use in the labelling of recyclable or reuseable hollow containers. The adhesive may be completely separated from the hollow containers and dissolved in an alkaline washing liquor even at low temperatures.

Abstract: To obtain an adhesive having both a high initial adhesive capacity and high heat resistance, a fusible adhesive which can be cross-linked by radiation and a low tendency to creep is provided. The adhesive contains 0 to 40 weight percent of at least one elastomer which cannot be cross-linked by radiation, 15 to 40 weight percent of at least one compound containing at least two olefinic double bonds, and 20 to 85 weight percent of at least one tackifier. The adhesive is especially suitable for use on high speed labeling machines.

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: Adhesive systems are useful for bonding wrap-around labels using an overlap adhesive in their application to blown plastic containers, more particularly plastic bottles.
