  • Publication number: 20110187018
    Abstract: The invention relates to an improved process for controlling the amount of crosslinking in polyolefin based articles such as fibers or films. The invention relates to mixing silane grafted material together with ungrafted material prior to crosslinking. The article can then be formed and cured, optionally with a curing catalyst which can preferably be applied to the surface of a shaped article. The amount of crosslinking will be controlled in part by the level of silane grafting on the grafted silane material as well as the amount of the grafted material in the blend.

  • Publication number: 20110178343
    Abstract: The present invention provides one-step processes for the production of chlorinated and/or fluorinated propenes. The processes provide good product yield with low, e.g., less than about 20%, or even less than 10%, concentrations of residues/by-products. Advantageously, the processes may be conducted at low temperatures relative to conventional processes, so that energy savings are provided, and/or at higher pressures so that high throughputs may also be realized. The use of catalysts may provide enhancements to conversion rates and selectivity over those seen in conventional processes, as may adjustments to the molar ratio of the reactants.

  • Publication number: 20110146309
    Abstract: Embodiments of the present disclosure include a process for the production of chlorine gas. For the various embodiments, the process includes compressing a gas mixture of vaporized liquid chlorine and a feed gas containing chlorine to form a compressed gas. Chlorine in the compressed gas is condensed into liquid chlorine. A first portion of the liquid chlorine is vaporized to provide a heat of condensation to condense chlorine from the compressed gas into liquid chlorine. A second portion of the liquid chlorine is vaporized to provide both the vaporized liquid chlorine for the gas mixture and a heat of condensation to cool a tail gas from the process. A chlorine gas product from the vaporized first portion of the liquid chlorine is also produced.
