A composition having flame retardant properties comprising a polymeric material and a bauxite as flame retardant filler dispersed in the polymeric material, wherein the bauxite has an aluminum hydroxide content of at least 50% by weight and is in the form of particles having an average size (d.sub.50) not higher than 8.0 ?m and a specific surface area (BET) not higher than 10.0 m.sup.2/g. These compositions provide excellent performance in terms of both self-extinguishing and mechanical properties, in particular elongation at break. Such compositions may be used to produce cable jackets for the transport or distribution of electrical energy and/or for telecommunications, panels and coverings for buildings, pipes, and the like.

The invention relates semiconductive polyethylene composition, for use in power cables, with improved smoothness compared to other available semiconductive polymer compositions. This invention relates to a cable with a layer comprising the semiconductive polyethylene composition.

The present invention is directed to an elastomer composition comprising an ethylene/-olefin/diene modified interpolymer, a very low density polyethylene component, and a propylene polymer component, wherein the propylene polymer component comprises at least one branched polypropylene.

This disclosure relates to a continuous solution three reactor polymerization process. Process solvent, ethylene, optional comonomers, optional hydrogen and a single site catalyst system are injected into a first and second reactor configured in parallel to one another. A third reactor receives effluent from the first reactor, the second reactor, or a combination of the first and second reactors. Fresh monomer is feed to the third reactor for further polymerization and to give a final polyethylene product.

The heat-recoverable article according to the present invention has a cylindrical shape and includes a base material layer. The base material layer contains a polyolefin-based resin. In the base material layer after being heated at 180 C. for 2 minutes, a melting-point peak temperature is 115 C. or higher and 128 C. or lower, a heat of fusion of a total resin component is 80 J/g or more and 150 J/g or less, a storage modulus at 120 C. is 4 MPa or more, a gel fraction is 40% by mass or more and 80% by mass or less, and a storage modulus at 180 C. is 0.5 MPa or more and less than 3.0 MPa. The polyolefin-based resin is preferably a mixture of a first polyolefin-based resin having a melting point of 125 C. or higher and 135 C. or lower and a second polyolefin-based resin having a melting point of lower than 125 C.
