Abstract: A reflection-type projection screen is provided having uniformly high gain over a wide range of viewing angles. The projection screen includes a dual-purpose light reflective, supportive substrate including at least one unpigmented flash-spun plexifilamentary film-fibril sheet having a light reflectance of greater than about 85% and a gloss of less than about 10% when measured at a 60° incident angle, and an optical diffusion layer of a light transmissive melt-processible polymer containing diffusion-enhancing particles covering at least one surface of the substrate. The projection screen has an optical gain of between about 0.90 and about 2.0 and the optical gain deviates by no more than about 8% over viewing angles between ?60° and +60°. The projection screen has good drapeability, rollability the ability to lay and hang flat. The projection screen can also be recycled.

Abstract: A process for treating acid gases comprising hydrogen sulfide comprises introducing a first acid gas and a first oxygen-containing gas into a reducing furnace to produce a first oxidized gas stream, cooling the first oxidized gas stream in a first heat recovery system, introducing the cooled gas stream into a sulfur condenser to produce a sulfur-stripped gas, introducing the sulfur-stripped gas and a second oxygen-containing gas into an oxidizing furnace to produce a second oxidized gas stream and cooling the second oxidized gas stream in a second heat recovery system. The first acid gas can be acid gas comprising hydrogen sulfide produced in refineries. The spent acid can be spent sulfuric acid from a sulfuric acid alkylation process. The cooled second oxidized gas stream can be further treated in a spent acid recovery plant or a sulfur recovery unit.

Abstract: Perfluorinated polyimides (and co-polyimide) compositions, particularly films are disclosed, comprising at least 50 mole percent of a polymeric repeat unit derived from contacting 3,3?,4,4?-biphenyltetracarboxylic dianhydride (BDPA) and 2,2?-bis(trifluoromethyl) benzidine (TFMB) monomers. The perfluorinated polyimide (and co-polyimide) films of the invention have an in-plane coefficient of thermal expansion (CTE) between ?5 and +20 ppm/° C. and a average light transmittance percent of from about 65.0 to about 99.0 (on a 75-micron thick film basis). The films of the present invention were converted to a polyimide using a chemical conversion method instead of typically employed thermal conversion step thus yielding these desirable properties. The films of the present invention can be an excellent substrate in an optical display device and can be used to replace rigid glass substrates. Finally, the polyimide films of the invention can also be used to manufacture flexible display devices (e.g.

Abstract: The present invention is a composition useful as an impact modifier for polyamide compositions. In one embodiment, impact modifiers of the present invention are ethylene maleic anhydride copolymers having at least 3% maleic anhydride functionality. Compositions comprising copolymers of ethylene and maleic anhydride or its functional equivalents and ethylene copolymers with polar comonomers are disclosed. The compositions provide miscible blends and exhibit improved properties, such as increased temperature resistance and mechanical strength, compared to pure ethylene copolymers with polar comonomers.
Abstract: The present invention relates to compositions of matter that are ionic liquids, the compositions comprising any of eleven cations combined with any of three fluorinated sulfonated anions. Compositions of the invention should be useful as solvents and, perhaps, as catalysts for many reactions, including aromatic electrophilic substitution, nitration, acylation, esterification, etherification, oligomerization, transesterification, isomerization and hydration.

Abstract: A method for measuring a layer of a device is provided. In an embodiment, a set of baseline reflectance profiles may be generated from a corresponding set of baseline devices. Each of the baseline devices may include a layer with a known thickness. A reflectance profile may also be generated from the device, which may include a layer with an unknown thickness. The reflectance profile generated from the device may then be compared to the set of reflectance profiles generated from the set of the baseline devices to determine the thickness of the layer of the device.

Abstract: A method for identifying shampoo-resistant hair-binding peptides is described. The shampoo-resistant hair-binding peptides bind strongly to hair from a shampoo matrix and are stable therein. Peptide-based benefit agents, such as peptide-based hair conditioners and hair colorants, based on the shampoo-resistant hair binding peptides are described. The peptide-based hair conditioners and hair colorants consist of a shampoo-resistant hair-binding peptide coupled to a hair conditioning agent or a coloring agent, respectively. Hair care and hair coloring product compositions comprising these peptide-based hair conditioners and colorants are also described.

Abstract: The present invention is directed to a novel high temperature polymerization process operating at high pressures for producing a polymer. The process includes conveying hybrid reactor mixtures, which include one or more hybrid reactor monomers and one or more hybrid reactor initiators to one or more hybrid reactors. The hybrid reactors are maintained at effective hybrid polymerization temperatures and sub-reflux polymerization gage pressures to cause polymerization of a portion of the hybrid reactor monomers into the polymer. The process further includes conveying hybrid reactor contents from the hybrid reactors to one or more batch reactors maintained at effective batch polymerization temperatures and reflux polymerization pressures to cause polymerization of a remaining portion of the hybrid reactor monomers into the polymer. The hybrid reactors are smaller in volume than the batch reactors.
