Abstract

A hot melt adhesive composition comprises a polymer comprising poly(α-methyl-β-propiolactone) (PMPL) or a derivative thereof, wherein the PMPL is polymerized from a plurality of (R)-α-methyl-β-propiolactone monomers and a plurality of (S)-α-methyl-β-propiolactone monomers, wherein the ratio of (R):(S) monomers is from about 90:10 to about 10:90. Changing the (R):(S) ratio impacts the isotactic diad fraction and consequently the crystallinity and thermomechanical properties of the resulting PMPL. The PMPL may be hydroxyl-terminated, with the residue thereof serving as the elastomeric B block in an A:B:A triblock copolymer having hard end A blocks, such as a residue of polylactic acid. The PMPL diol may also be used as a reactant to form an alkoxysilane-terminated polymer, a polyurethane, or a (co)polyester. In some embodiments, such triblock polymers may be entirely bio-sourced and compostable.

Abstract

11 is an alkyl group having at least 8 carbon atoms. The macromolecule may be hydroxy-terminated, and may be copolymerized with other β-lactone monomers having different substituting groups and/or with higher lactone monomers. The macromolecule may be used as a reactant to form an alkoxysilane-terminated polymer, a polyurethane, or a (co)polyester, or may be used as an elastomeric midblock in a triblock copolymer having hard end blocks, such as polylactic acid. Such triblock systems demonstrate two discreet regions having properties similar to styrene block copolymers and are therefore suitable for use as hot melt or pressure-sensitive adhesives. In some embodiments, such triblock polymers may be entirely bio-sourced and compostable.

Abstract

A hot melt adhesive composition comprises a combination of polymers including a low molecular weight semicrystalline propylene based polymer and a high molecular weight essentially amorphous propylene based polymer, both of which are prepared by using single-site catalysts, along with a wax, a hydrogenated styrene block copolymer, a tackifier, and a plasticizer. The composition has suitable viscosity ranging from 500 cP to 40,000 cP at 177°C and is useful for a variety of industrial applications where bonding of low surface energy substrates and elastic substrates is encountered, including disposable nonwoven hygienic articles. The cooled adhesive in the laminate does not feel hard but instead has a soft feel, even though the adhesive demonstrates a relatively high Shore A hardness.

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.

Abstract

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.
