  • Patent number: 8816003
    Abstract: This invention involves a composition, a method of making, and an application of high plasticization-resistant chemically cross-linked polymeric membranes such as cross-linked cellulose acetate (CA) membrane. These cross-linked polymeric membranes with covalently interpolymer-chain-connected rigid networks showed no decrease in CO2/CH4 ideal selectivity under 690 kPa (100 psig) pure CO2 pressure and also no CO2 plasticization up to 3447 kPa (500 psig) pure CO2 pressure. By using the method of chemical cross-linking as described in this invention, the separation characteristics of the polymeric membranes can be decisively improved. These new cross-linked polymeric membranes can be used not only for gas separations such as CO2/CH4 and CO2/N2 separations, O2/N2 separation, olefin/paraffin separations (e.g. propylene/propane separation), iso/normal paraffins separations, but also for liquid separations such as pervaporation and desalination.

  • Publication number: 20140227589
    Abstract: A polymer of the present invention has a plurality of pendant groups. Each of the pendant groups is constituted of a carboxyl group or a salt thereof, and a group interposed between a main chain and either the carboxyl group or salt thereof. The group interposed between the main chain and either the carboxyl group or salt thereof is: a hydrocarbon group; a perfluorocarbon group; constituted of a hydrocarbon group and at least one of an ester group and a carbonate group; or constituted of a perfluorocarbon group and at least one of an ester group and a carbonate group. A carbonyl carbon included in the carboxyl group or salt thereof is bonded directly to a carbon included in either the hydrocarbon group or the perfluorocarbon group.

  • Patent number: 8795803
    Abstract: A laminate film including a first core polylactic acid layer, a coating receiving-layer of polylactic acid, and coated on one side of the coating receiving-layer with PVOH, EVOH, a blend of crosslinked EVOH/PVOH, vinyl alcohol-vinylamine (PVAm) copolymer, anionic carboxylated styrene-butadiene copolymer (SBR) emulsion, or blends thereof. This coating may be applied after the machine-direction orientation step and dried and oriented in a transverse direction orientation oven if in-line coating is desired; or applied to the film in an off-line coating method and dried in an air flotation oven. The dried coating layer can be metallized. This laminate film exhibits excellent gas and moisture barrier properties, appearance, and metal adhesion. It may also optionally include a heat sealable or winding improving layer on the side opposite the coating receiving-layer of the core layer.

  • Patent number: 8796381
    Abstract: Encapsulated cure systems are provided wherein a curative is incorporated into a solid or semi-solid carrier material whereby mere fracturing or failure of the capsule wall encapsulating such cure systems will not provide for or allow sufficient release of the curative. Also provided are adhesive systems incorporating said encapsulated cure systems.

  • Publication number: 20140137310
    Abstract: The present development is a liner unit comprising a light-weight polymeric material that becomes cold when exposed to water, which can be used to line a soft-crown cap, such as a baseball cap. The liner is sized to fit snuggly within the cap, and may be reversibly attached to the interfacing of the cap. Alternatively, the liner may comprise a magnet, sized and oriented on the liner so as to allow the magnet to engage with the underside of a button secured to the cap.

  • Patent number: 8728593
    Abstract: A water-soluble film which comprises a saccharide component and a vinyl alcohol resin component, where the vinyl alcohol resin may include functional comonomer units such as sulfonic acid functional groups or salts thereof. Preferred are polyvinyl alcohol/2-methylacrylamido-2 methyl propane sulfonic acid resins (PVOH/AMPS) which may be purchased commercially with relatively higher or relatively lower characteristic viscosity. The films exhibit superior resistance to aggressive oxidizing chemicals and remain soluble in water after prolonged exposure thereto. The films are particularly useful for unit-dose packaging of chlorine-containing pool chemicals, such as trichloroisocyanuric acid.

  • Patent number: 8722785
    Abstract: Provided is a composite of saponified product of an ethylene-vinyl ester-based copolymer from which films excellent in gas barrier properties and film rigidity and highly inhibited from having fish eyes are obtained. It is a process for producing a composite of saponified product of an ethylene-vinyl ester-based copolymer, which comprises: mixing a composition (a) containing a saponified product of ethylene-vinyl ester-based copolymer (A1) and having a moisture content of 50% by weight or higher with a water-swellable layered inorganic compound (B) to obtain a composition (C); and mixing the composition (C) in the state of having a moisture content of 10% by weight or higher and less than 60% by weight with a saponified product of ethylene-vinyl ester-based copolymer (A2).

  • Patent number: 8703868
    Abstract: Ethanol is produced from methyl acetate by a hydrogenolysis reaction. The methyl acetate is produced as a byproduct during the conversion of a vinyl acetate polymer or copolymer to a polymer or copolymer of vinyl alcohol. By integrating the two processes, a valuable product, i.e. ethanol, is produced from a methyl acetate byproduct.

  • Patent number: 8697802
    Abstract: Acetic acid is converted to vinyl acetate monomer by a reaction with oxygen and ethylene. The vinyl acetate is polymerized to form a vinyl acetate polymer or copolymer, which is then reacted in a methanolysis reaction with methanol and base to form a polymer or copolymer of vinyl alcohol and a methyl acetate byproduct. Ethanol is produced from methyl acetate by a hydrogenolysis reaction. The hydrogenolysis reaction also produces methanol. At least a portion of this ethanol is converted to ethylene by a dehydration reaction. At least a portion of the ethylene produced in this dehydration reaction is recycled to react with acetic acid and oxygen to form vinyl acetate. By converting a byproduct and by recycle of compositions, a polymer or copolymer of vinyl alcohol is efficiently produced with minimal waste.
