    Abstract: Disclosed is a high-pressure gas hose or storage vessel comprising at least one layer of a resin composition comprising (A) 1,2-diol in a side chain-containing vinyl alcohol-based resin, and (B) fluororesin having polar functional group capable of reacting with or forming hydrogen bond(s) with hydroxyl group. The gas-barrier layer comprising the resin composition has a favorable wettability of the interface between the component (A) and the component (B), and therefore the gas-barrier layer exhibits high level gas-barrier property without causing blister under the condition of high pressure of not only oxygen or air but also small molecule gas such as hydrogen. Furthermore, the gas barrier layer has superior flexibility and superior durability with respect to changes accompanying the supply and removal of high-pressure gas.

  • Patent number: 9034447
    Abstract: The present invention provides a new design for high capacity stationary phases for dianion selective ion chromatography. The stationary phases include one or more layers which are products of condensation polymerization. Multiple components are of use in forming the first polymer layer and the condensation polymer structure, thereby providing a stationary phase that can be engineered to have a desired property such as ion capacity, ion selectivity, and the like. Exemplary condensation polymers are formed by the reaction of at least one polyfunctional compound with at least one compound of complimentary reactivity, e.g., a nucleophilic polyfunctional compound reacting with an electrophilic compound.

  • Patent number: 9023445
    Abstract: A composite container for storing perishable products may include a composite body and a composite bottom. The composite bottom may include a bottom fiber layer, a bottom oxygen barrier layer, and a bottom sealant layer, such that the composite bottom has an upper surface and a lower surface. A hermetic seal may be formed between a sealing portion of the composite bottom and an interior surface of the composite body. When an internal pressure is applied to the interior surface of the composite body and the upper surface of the platen portion of the composite bottom, an external pressure is applied to the exterior surface of the composite body and the lower surface of the composite bottom, and the internal pressure is about 20 kPa greater than the external pressure, the platen portion of the composite bottom may not extend beyond the bottom edge of the composite body.

  • Patent number: 8999468
    Abstract: A transparent article includes a continuous polyester matrix having at least one incompatible filler dispersed therein. The incompatible filler provides domains in the polyester matrix, each domain having a particular dimension, thus providing a range of dimensions for the domains in the article. To create haze, the dimensions are within the range of from about 380 nm to about 720 nm. Once the range of dimensions is determined, a light absorbent composition can be found which absorbs light at a range of wavelengths that at least substantially covers the range of dimensions of the domains. In doing so, it has been found that the haze of the article can be substantially masked. Method for producing the article and for masking the haze are also provided.
