  • Hot melt adhesive compositions based on propylene-based polymers and methods for using same
    Patent number: 11365329
    Abstract: A polymer composition for use in a hot melt adhesive comprises at least one semierystalline, low molecular weight (LMW) propylene-based polymer; at least one essentially amorphous, high molecular weight (HMW) propylene-based polymer; and at least one essentially amorphous, LMW propylene-based polymer. A hot melt adhesive composition further contains a tackifier, a plasticizer, an antioxidant, and optionally a wax, a filler, a colorant, a UV absorber, another polymer, or combinations thereof. The hot melt adhesive is useful for a variety of industrial applications where bonding of low surface energy substrates is encountered, including disposable nonwoven hygienic articles, labeling and other assembly applications.
