Abstract

Adhesives comprising a silyl-terminated polyether and a tackifying resin provide a considerably reduced tack at relatively slight increases in temperature, undergo purely adhesive failure at such increased temperatures, and have reversible properties (i.e., such properties are substantially retained upon cooling). Such adhesives may be used to reversibly bond a first substrate surface coated with the adhesive to a second substrate surface by adhering the substrate surfaces together at a first temperature; heating the adhesive to a second temperature at least about 20° C. above the first temperature and below the thermal degradation temperature; and separating the substrate surfaces from one another at the second temperature, wherein the adhesive comprises the cured product of a silyl-terminated polyether and a tackifier. Such adhesives may also be cleanly transferred from to a different substrate at such elevated temperatures. Such adhesives may be used for tapes suitable for easy removal at elevated temperatures.

A hot melt adhesive composition comprises a polypropylene homopolymer having a DSC melting point of less than 100° C.; a butene-based copolymer; and a plasticizer. The butene-based copolymer may comprise a butene-rich amorphous poly-alpha olefin, such as a butene-propylene copolymer, or a semi-crystalline copolymer, such as a butene-ethylene copolymer. The hot melt adhesive is especially useful for bonding substrates which swell or elongate significantly in use. Such uses include adhering superabsorbent polymers to a substrate or adhering together two substrates at least one of which having superabsorbent polymers, such as the top and bottom layer of an absorbent core of a disposable hygiene article, such as a diaper, feminine sanitary napkin, and adult incontinence pad. The hot melt adhesive composition, which does not contain a tackifier, demonstrates suitable elongation at break and stress at yield, with a sufficiently low viscosity, to stabilize an absorbent core having superabsorbent polymers.
