    摘要: An olefin production system having a pyrolysis furnace that is configured to thermally crack hydrocarbon feedstock into olefins and a fuel gas system having a hydrotreater system that is configured to hydrogenate process gas. The pyrolysis furnace has a burner and the fuel gas system is configured to supply the hydrogenated process gas as fuel gas to the burner.

    摘要: A clay-filled polyolefin composition and process for making it are disclosed. The process involves treatment of a non-acid-treated smectite clay with a Ziegler-Natta catalyst in the presence of a hydrocarbon and subsequent polymerization of an olefin in the presence of the treated clay and an organoaluminum cocatalyst. Results indicate that filled compositions produced by this process contain exfoliated clay.

    摘要: This disclosure provides for compatibilizer compositions that are useful in compounding polypropylenes and ethylene elastomeric copolymers for injection molding applications. The compatibilizer includes a combination of: Component A of polypropylene homopolymers or polypropylene copolymers containing small amounts of ethylene; and Component B of propylene bipolymers with ethylene and/or other α-olefin comonomers, the bipolymer having a relatively high proportion of propylene moieties, for example, 50-75% propylene. Compared to known or conventional compatibilizer formulations, the bipolymer Component B is relatively propylene rich and generally can be used in the injection molding composition in lower concentrations.

    摘要: The present disclosure provides a method for crosslinking polyolefins through using a substantially-miscible, polyolefin-based, silane-crosslinking-agent carrier and related moisture-crosslinkable polyolefin-based compositions. The method is for crosslinking a first polyolefin includes the steps of: (A) selecting a second polyolefin being substantially-miscible with the first polyolefin and having particles of a morphology selected from the group consisting of powder and substantially spherical; (B) admixing the second polyolefin to the first polyolefin; (C) adsorbing a silane-crosslinking agent onto the second polyolefin, thereby rendering a substantially-miscible, polyolefin-based, silane-crosslinking-agent carrier; (D) melt blending the first polyolefin and the substantially-miscible, polyolefin-based, silane-crosslinking-agent carrier, thereby yielding a moisture-crosslinkable polyolefin-based composition; and (E) crosslinking the moisture-crosslinkable polyolefin-based composition.

    摘要: The present disclosure provides a peroxide-modified polyethylene, related compositions, and wire-and-cable products made therefrom. The process for preparing the peroxide-modified polyethylene including the steps of: (A) preparing a first Ziegler-Natta-catalyzed polyethylene in a first reactor; (B) transferring the first Ziegler-Natta-catalyzed polyethylene from the first reactor to a second reactor; (C) admixing a first amount of an organic peroxide to the second reactor; (D) reacting the organic peroxide with a polyethylene composition made from or containing the first Ziegler-Natta-catalyzed polyethylene, thereby coupling the polyethylene components and forming the peroxide-modified polyethylene; and (E) collecting the peroxide-modified polyethylene.
