The present disclosure provides a coated conductor. The coated conductor includes a conductor and an outermost coating on the conductor. The coating includes (A) an ethylene-based polymer having an I21/I2 ratio from 20 to 50; and (B) a propylene/ethylene copolymer having a Mw/Mn from 2.0 to 3.5. The coating has a surface roughness from 20 μ-inch to 100 μ-inch.

The present disclosure provides a process. In an embodiment, the process includes blending a broad molecular weight distribution (MWD) ethylene-based polymer having an 121/12 ratio from 55 to 85 with a narrow MWD ethylene-based polymer having an 121/12 ratio from 20 to 50. The process includes forming a blend component comprising from 20 wt % to 45 wt % of the broad MWD ethylene-based polymer, from 80 wt % to 55 wt % of the narrow MWD ethylene-based polymer, and optional carbon black. The blend component has a density from 0.925 g/cc to 0.955 g/cc and an 121/12 ratio from 30 to 55. The process includes extruding the blend component over a conductor at a rate greater than 1.02 m/s, and forming a conductor jacket having a surface smoothness from 30 &#x3bc;-inch to 80 &#x3bc;-inch.

A metallized optical fiber comprises: A) An optical fiber, and B) A conductive metal over and in contact with the optical fiber and having a thickness that is at least 0.15 times the thickness of the optical fiber. The metallized optical fiber can form a component of a hybrid optical fiber/coaxial cable, and it provides good protection against interference with the data signal traveling along the optical fiber from electrical current from an adjacent or near-by electrical conductor.

Metallized optical fiber

Conductive cores for use in cables, where the conductive core comprises a filled-polymeric-composite material concentrically surrounded by a conductive layer. The filled-polymeric-composite material comprises a polymeric continuous phase having dispersed therein a filler material. Such conductive cores can be employed in various cable designs and further include one or more outer layers, such as dielectric insulation layers, conductive shield layers, and jackets.

Cable with polymer composite core

Polymeric compositions having a slip agent comprising a silicone and a fatty acid amide. Such polymeric compositions can exhibit lower coefficients of friction when compared to polymeric compositions containing either silicone or fatty acid amide alone. Such polymeric compositions are suitable for use in various articles of manufacture, including, for example, wire and cable jackets.

Plastic optical fibers or plastic optical fiber cores with good high temperature resistance to optical attenuation loss are prepared from a cyclic block copolymer characterized by a: A. Weight ratio of hydrogenated conjugated diene polymer block to hydrogenated vinyl aromatic polymer block of 35:65 to 10:90; B. Number average molecular weight (Mn) of from 40,000 to 150,000, grams per mole (g/mol); and C. Hydrogenation level such that each hydrogenated vinyl aromatic polymer block and each hydrogenated conjugated diene polymer block has a hydrogenation level of at least 95 percent.

The present disclosure provides a process for producing low density polyethylene with a dissipation factor less than or equal to 1.48&#xd7;10radian at 2.47 GHz. The process includes free radical high pressure polymerization of ethylene and separation of the unreacted species from the resultant polyethylene to form a recycle stream. The process further includes purging dissipative components from the recycle stream. The purged recycle stream is then introduced into the polymerization reactor.
