Abstract: Disclosed are adhesives and processes for preparing the same, comprising at least one first homogeneous ethylene/?-olefin interpolymer, and optionally at least one tackifier, and optionally at least one plasticizer. The claimed adhesives are useful as adhesives such as are employed in various applications, such as in masking tape, clear office tape, labels, decals, bandages, decorative and protective sheets (such as shelf and drawer liners), floor tiles, sanitary napkin/incontinence device placement strips, sun control films, the joining of gaskets to automobile windows, packaging, bookbinding, construction of nonwoven articles, and insulation bonding.

Abstract: A hot melt adhesive composition comprising from about 5% to about 15% by weight of at least one radial styrene-isoprene-styrene block copolymer having the general configuration (pS--pI--pB).sub.n X wherein n is a number greater than 2, said block copolymer having a molecular weight from about 90,000 to about 380,000, and preferably from about 100,000 to about 250,000, and a styrene content from about 15% to about 35% by weight, and preferably from about 20% to about 30% by weight; up to about 10% of a compatible polymer, wherein the total polymer content does not exceed 15%; from about 30% to about 60% by weight of at least one compatible tackifying resin; from about 20% to about 40% by weight of at least one compatible plasticizer; and from about 0.1% to about 2% by weight stabilizer.

Abstract: Hot melt adhesives of this invention can comprise a water-soluble polyalkylenimine, an hydroxy substituted organic compound, and optimally a plasticizer, a tackifier, and other ingredients. The adhesives are water actuated, and can be water activated, cleaned by aqueous systems, or recycled in aqueous systems.

Abstract: Normally water insoluble hot melt adhesive compositions containing structural polymers such as A-B-A block copolymers, butyl rubbers, polyesters, ethylene vinyl acetates, ethylene acrylic acid polymers can be made sensitive to the action of water using an effective water sensitizing amount of a polyalkyloxazoline polymer in the hot melt adhesive. The polyalkyloxazoline polymer can be incorporated into a single phase adhesive composition with the structural polymer using an effective amount of a hydroxyl or carboxylic acid compound.

Abstract: The adhesive properties of a hot melt adhesive, comprising a base polymer and a tackifying resin, can be improved by introducing into the hot melt adhesive an epoxy adduct comprising the reaction product between a compound such as a polymer having at least one active hydrogen and an epoxy compound.
