  • Publication number: 20120046401
    Abstract: A method for improving the efficacy of polar additives used in polyolefins is disclosed. The method is related to the addition of an effective amount of a co-additive compound of the formula R1(OCH2CH2)xOH to the polyolefin prior to forming the film, wherein R1 is a straight or branched chain alkyl of 20 to 100 carbon atoms and x is 2 to 100. The presence of these materials in polyolefin resins allows less polar additives to be used without losing their efficacy and also leads to improved optical properties for films made from such resins.

  • Publication number: 20110305865
    Abstract: A sound- and vibration-dampening (NVH) layered composition may be prepared by spraying or spray-foaming a polyurethane heavy layer, and spray-foaming a flexible polyurethane foam layer, under conditions such that the two layers bond integrally with one another without use of glue or other adhesive. Additional layers, that are the same as, or different from, these two layers may also be included in the composition. The layered composition may be used in, for example, automotive applications. The method is faster and requires less hardware and space than conventional methods that include gluing steps or employ heavy molds to withstand the pressures generated therein by methods such as injecting or pouring; however, it may still attain relatively uniform thicknesses even when spraying is done on a substrate that does not become part of the final construction.

  • Publication number: 20110228630
    Abstract: Excessive residence time in the conduits located between the outlet of a static mixer and a reactor/separator reservoir can lead to undesired by-products, formation of solids, and conduit fouling. This disclosure relates to an improved configuration for a static mixer with reduced transitory time to help reduce the creation of undesired by-products and fouling during the process of mixing, and more particularly to a phosgene reactor comprising a short or very short conduit for reducing the transit time from the static mixer to a reactor/separator reservoir to one second or less.

  • Publication number: 20110230679
    Abstract: This disclosure relates to a static phosgene mixer, and more generally, to an apparatus for mixing of fluid components such as phosgene and amine during an highly reactive, chemical reaction that is vulnerable to the creation of undesired by-products, and equipment fouling. A guide element is disposed in the static mixer to divert the incoming flow of phosgene around the guide element and create an annular mixing passage in the static mixer. This allows for the use of an increased external radius of the effective phosgene flow while maintaining phosgene velocity by creating a blockage of the flow. The same flow, when transformed from a circular configuration to an annular configuration has an increased external radius, and a greater quantity of MDA jets can be placed along the increased radius, thus increasing the overall homogeneity of the mixture.
