A multi-modal polymer blend of at least three fractions as determined by TREF is provided. The blend comprises a first propylene-based polymer, a second propylene-based polymer; and a third propylene-based polymer; wherein when subjected to TREF, the polymer blend exhibits: a first fraction that is soluble at &#x2212;15&#xb0; C. in xylene, the first fraction having an isotactic (mm) triad tacticity of about 55 mol % to about 85 mol %; a second fraction that is insoluble at &#x2212;5 C in xylene or dichlorobenzene and soluble at 40&#xb0; C. in xylene or dichlorobenzene; and a third fraction that is insoluble at 70&#xb0; C. in xylene or dichlorobenzene and having an isotactic (mm) triad tacticity of about 85 mol % to about 98 mol %. Also provided are hot melt adhesive compositions comprising the polymer blend, tackifier, wax; and optionally a nucleating agent, articles containing the adhesive and methods of fabricating the articles.

Multi-modal polymer blend, hot melt adhesive comprising same and use thereof

The present invention relates to an adhesive, comprising at least one polymer system obtained by a process for reducing the melt viscosity of at least one polymer blend starting material, wherein the process comprises the step of treating at least one polymer blend with at least one radical donor under shear stress at a temperature above the softening point of said polymer blend.

Adhesives made from polymer systems

The present invention relates to a process for manufacturing an adhesive by extrusion, wherein the adhesive comprises at least one degraded polypropylene(co)polymer and at least one additional additive.

Process for manufacturing an adhesive by means of extrusion

The invention relates to a hotmelt adhesive based on at least one ethylene and/or propylene/Cto C&#x3b1;-olefin copolymer obtainable by metallocene-catalysed polymerization, on at least one tackifying resin, and on at least 0.1% to 15% by weight of a copolymer or terpolymer based on Cto Colefins with (meth)acrylic esters of low molecular mass alkanols, the copolymer containing COOH groups or anhydride groups, and also, if desired, on wax and additives, and to its use for bonding finished substrate surfaces.

Hotmelt adhesive with improved adhesion

Hot-melt adhesives containing at least one aromatic modified polyethylene and/or polypropylene (co)polymer, a further ethylene or propylene/C4 to C20 alpha-olefin copolymer, and at least one tackifying resin are useful for the adhesive bonding of package and paperboard products.

Hot-melt adhesive

The present invention pertains to an arrangement for the controlled application of adhesive to substrate. In at least one embodiment, the arrangement comprises a) an adhesive reservoir, b) a pump, c) an applicator head having at least one applicator nozzle, d) a volume throughput sensor, and e) a monitoring unit. The reservoir, the pump, and the applicator head are connected together by a conduit system carrying the adhesive. The volume throughput sensor and the monitoring unit are connected together by a pulse transmission line. The monitoring unit, the feed pump, and the applicator head are connected together by control lines. In at least one embodiment, the application of adhesive to substrates is controlled by measuring the volume throughput of the adhesive, transmitting signals indicative of volume throughout to the monitoring unit, and controlling the amount of adhesive applied to the substrate material in-line in response to the signals.
