    摘要: Disclosed are hot melt adhesives comprising at least one first homogeneous linear etylene polymer having a particular density and melt viscosity at 350.degree.F. (177.degree.C.), and an optional wax and tackifier. In particular, disclosed is a hot melt adhesive characterized by: a) at least one homogeneous linear or substantially linear interpolymer of ethylene with at least ibe C.sub.2 --C.sub.20 .alpha.-olefin interpolymer having a density from 0.850 g/cm.sup.3 to 0.895 g/cm.sup.3 ; and b) optionally at least one tackifying resin; and c) optionally at least one wax wherein the hot melt adhesive has a viscosity of less than about 5000 cPs (50 grams/cm.second) at 150.degree.C. Preferred hot melt adhesives for use in adhering cardboard or paperboard are disclosed, as well as the resultant adhered products. Also disclosed is a dual reactor process for the preparation of the inventive hot melt adhesives.

    摘要: A hot melt adhesive comprises an ethylene α-olefin copolymer, an acid anhydride modified polyolefin and a hydrogenated tackifying resin. The hot melt adhesive has excellent viscoelastic properties and can be used in a variety of applications. In one application, attaching an elastic band to a flexible film, the adhesive has excellent viscosity and, in a finished absorbent article, a minimal creep characteristic. Also disclosed is a disposable article using the adhesive to adhere adjacent surfaces within the disposable article including an elastic band to a polyolefin backing film, for example, in a diaper, incontinent article or other such structure.

    摘要: A novel spray-on adhesive composition is made from a high melt index polymer and a rosin ester tackifier that interact to produce a composition that can form a low VOC, non-tacky, hot melt adhesive material that can be used in disposable article manufacture. The adhesive provides surprisingly high initial adhesion. Additionally, the adhesive is thermally stable at hot melt application conditions, low in cost, easily applied, and produces high quality disposable articles.
