  • Propylene-based amorphous poly-alpha-olefins (APAOs) formulated with hexene-1 monomer containing amorphous poly-alpha-olefins for use in hot melt adhesives
    Patent number: 10160888
    Abstract: Amorphous poly-alpha-olefins (APAOs) such as propylene-co-hexene-1-co-butene-1 and propylene-hexene-1 are used as tackifiers in hot melt adhesive formulations.
    Type: Grant
    Filed: September 27, 2016
    Date of Patent: December 25, 2018
    Inventors: Andres Sustic, Nick Fowler, Enrico Buenacosa, James Haselman
  • Performance APAO hot melt adhesives containing high melt flow rate hydrogenated styrene block copolymers
    Patent number: 9982098
    Abstract: Adding a compatible high melt flow rate (MFR), low melt viscosity, hydrogenated styrene block copolymer to amorphous poly alpha-olefins (APAOs) results in adhesives that show acceptably high elongation and tensile strength, and which, when applied by different hot melt application methods onto elastic strands, result in personal hygiene article components that perform comparably to such components assembled using just styrene block copolymer components formulated with compatible tackifiers, processing oils and other additives.

  • APAO-based hot melt adhesives
    Publication number: 20150148473
    Abstract: Ethylene-co-propylene-co-butene-1 terpolymers, made either with or without an in-reactor-added organosilicon external donor, are used in the formulation of improved-performance, APAO-based, hot melt adhesives.

  • Bi-modal Poly-alpha-olefin Blend
    Publication number: 20120178333
    Abstract: A low viscosity, high tensile strength polymer having a bi-modal molecular weight distribution is produced using a combination of high molecular weight polymer and low molecular weight polymer. The polymer chains have a high content of meso dyads that results in a greater amount of crystalline regions when the polymer is solidified. The low molecular weight chains provide high flow characteristics when the polymer is molten. The process for producing the high content of meso dyads includes the use of an external donor catalyst during the reaction.
