  • Publication number: 20150104639
    Abstract: A composition comprising a hot melt pressure-sensitive adhesive comprising a propylene-based polymer component, wherein the propylene-based polymer component has a MFR of greater than about 1,000 g/10 min to less than about 10,000 g/10 min, and free of or having a low block copolymer content. Also, an adhesive article comprising the composition.

  • Patent number: 8431642
    Abstract: Provided are adhesive compositions composed of a polyolefin composition comprising at least about 50 wt. % polypropylene and at least one wax. The polymer compositions have a Dot T-Peel of about 1 Newton or more, a branching index (g?) of 0.95 or less measured at the Mz of the polymer, a molecular weight of 100,000 or less, and the adhesive compositions has a fast set time. The packaging industry desires adhesive compositions having a fast set time, such as those setting in less than five seconds from a molten state at conventional packaging operating temperatures to a solid or quasi solid having favorable Dot T-Peel, set time, and or fiber tear adhesion properties. Polymer based adhesives performing within this window are a favorable alternative to conventional formulated adhesives. The provided adhesive compositions exhibit a favorable balance of properties such as high adhesive strength, wide temperature operating window, and fast set time.

  • Patent number: 7244787
    Abstract: Compositions are provided having from 70 wt % to 95 wt % of a polymer selected from homopolymers and random copolymers of propylene and from 5 wt % to 30 wt % of a miscible hydrocarbon resin with a glass transition temperature greater than 20° C. The polymer has a heat of fusion of less than 50 J/g, a melt index (MI) of less than 20 dg/min, and contains stereoregular propylene crystallinity. Also provided are films containing such compositions, and articles, such as diapers or incontinence garments, including such films.
