Abstract: A roofing underlayment capable of adhering to a roof deck comprising: (a) a roofing membrane having a first and a second major surface; and (b) a pressure-sensitive adhesive disposed on the first major surface of the roofing membrane and comprising: (i) at least one of butyl rubber or polyisobutylene; (ii) a first liquid plasticizer, preferably polybutene; and (iii) a tackifier, wherein the Tg of the adhesive is at most about 100 C. The adhesive provides high bond strength and excellent long-term heat aging, weathering resistance, as well as good low temperature properties while providing a moisture proof seam. A method for making the roofing underlayment includes applying the adhesive to the membrane then applying a release liner over the adhesive layer. A method for using the roofing underlayment comprises removing the release liner then adhering the underlayment to the roof deck by contacting the first to the roof deck.

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.

Abstract: A hot melt adhesive made from a blend of a polypropylene-based polymer, a polyolefin elastomer, and an amorphous polyolefin. These adhesives exhibit excellent molten and pre-set flow allowing them to wet out substrates yet develop properties needed to form and maintain strong bonds making them useful for hygiene, construction, and packaging applications.

Abstract: A laminate comprises a primary substrate and a secondary substrate mated with the primary substrate through contact with a hot melt adhesive. The hot melt adhesive comprises a polymer blend based on 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. The composition further contains a compatible tackifier, a plasticizer, an antioxidant, and optionally a wax, a filler, a colorant, a UV absorber, another polymer, or combinations thereof. Particularly preferred applications include nonwoven disposable diaper and feminine sanitary napkin construction, diaper and adult incontinent brief elastic attachment, diaper and napkin core stabilization, diaper backsheet lamination, industrial filter material conversion, and surgical gown and surgical drape assemblies.
