Abstract: The present invention relates to a polyolefin fiber comprising polymeric structures, wherein the polymeric structures individually comprise a polycondensate and a functionalized polymer, and the polyolefin fiber is a gel-spun high-performance polyethylene fiber that has a tenacity of at least 1 N/tex. The polymeric structures are immiscible with and dispersed in the polyethylene fiber. The gel-spun high-performance polyethylene fiber is a gel-spun ultrahigh molecular weight polyethylene fiber.

Abstract: Composite panel comprising at least one layer containing at least one tape comprising a thermoplastic polymer selected from the group consisting of polyolefins, polyesters, polyvinyl alcohols, polyacrylonitriles, polyamides or polyketone, wherein the tape has a tensile strength of at least 1.2 GPa and an areal density of between 5 and 150 g/m2, and an adhesive in contact with said layer, whereby the amount of the adhesive in contact with one side of the at least one layer is between 0.2 and 15 g/m2, wherein the adhesive is a plastomer wherein said plastomer is a random copolymer of ethylene or propylene and one or more C2 to C12 a-olefin co-monomers and wherein said plastomer has a density as measured according to 1801183 of between 860 and 930 kg/m3. In a preferred embodiment the tape comprises an ultra high molecular weight polyethylene. The composite panel is used in a ballistic resistant article.
