Abstract: Foam compositions comprise at least an ethylene/?-olefin interpolymer. The ethylene/?-olefin interpolymers of the present disclosure are multi-block copolymers comprising at least one soft block and at least one hard block. The foam compositions can further comprise a blowing agent and a cross-linking agent. Methods of making the foam compositions and foamed articles made from the foam compositions are also described.

Abstract: The present invention is a telecommunications cable comprising a plurality of electrical conductors, each conductor being surrounded by a layer of insulation comprising a coupled propylene polymer. It is preferable that the propylene polymer be an impact modified propylene polymer, more preferably an impact propylene polymer. The primary advantages of the insulation composition are realized under high-speed extrusion conditions for thin-walled insulation application, including the advantages of smooth insulation surface, good dimensional uniformity, and relatively low extrusion head and die pressures.
