摘要： A hotmelt adhesive composition includes a polymer produced from ethylene, one or more branched vinyl ester monomers, and optionally, vinyl acetate, and a tackifier. A method for producing the hotmelt adhesive composition includes adding a polymer produced from ethylene, one or more branched vinyl ester monomers, and optionally, vinyl acetate and a tackifier into a mixer, optionally adding wax and/or antioxidant into the mixer, and mixing the polymer and the tackifier, and the optional wax and/or antioxidant at a temperature in a range from 150° C. to 200° C. to form the hot melt adhesive composition. A method for bonding a substrate to a similar or dissimilar substrate includes applying the hotmelt adhesive composition to at least one substrate; and bonding the substrate and the hotmelt adhesive composition together. A multi-layer article comprises at least one layer of the hotmelt adhesive compositions and one or more substrate layers.

摘要： A method of controlling long chain branching in an ethylene-based polymer includes polymerizing ethylene with one or more optional monomers to form an ethylene-based polymer, and controlling a degree of long chain branching (LCB) in the ethylene-based polymer. The degree of LCB ranges from 0.1 per 1000 carbon atoms in the polymer backbone to 10 per 1000 carbon atoms in the polymer backbone, as measured by 13CNMR. The degree of LCB is controlled by adding one or more branched vinyl ester to the polymerizing step in an amount ranging from 0.01 mol % to 5.0 mol %, relative to total monomer content. A polymer composition contains the ethylene-based polymer. An article includes the polymer composition containing the ethylene-based polymer.
