Described herein are polymerblends having improved impact performance and outstanding chemical resistance. The polymerblends include at least one semi-aromatic polyester polymer, at least one poly(phenyl sulfone) polymer, and at least one impact modifier. In some embodiments, the polymerblends can optionally include one or more aromatic polycarbonate polymers, one or more poly(aryl ether sulfone) polymers and one or more additives. In some embodiments, the polymerblends can be desirably incorporated mobile electronic device components.

Described herein is a melt-processible polymer composition comprising: a non-fluorinated melt-processible polymer; and a fluorine-containing polymer comprising at least three (SO.sub.3.sup.)iM.sup.+i groups per polymer chain wherein M is a cation; and i is an integer.

Additional oil recovery is obtained from a reservoir with a composition comprising at least a coupling solvent typically employed in waterborne coating compositions. Provided herein are embodiments of methods of recovering hydrocarbons using at least one coupling solvent, such as an oxygenated coupling solvent. The coupling solvent increases the mutual solubility with water at the injection temperature to facilitate the mixing and injection, particularly with an optional co-solvent. The coupling solvent helps mitigate formation plugging and improve performance when injected into a formation, as the solvent mixture moves from being miscible in the injection field water to being miscible in the reservoir oil, mobilizing the reservoir oil to increase oil recovery.

The present invention addresses the problem of providing a crosslinked film and a hydrocarbon-based proton conducting solid electrolyte having a proton conductivity equal to that of a perfluorosulfonate ion exchange polymer. Disclosed as a means for solving this problem is a proton conducting polymer electrolyte which is composed of a sulfonated polyphenyl compound having a plurality of repeating units, and wherein two or more (for example, four or six) sulfonic groups are introduced into one repeating unit on average. The sulfonated polyphenyl compound may be a polymer or copolymer having a skeleton structure selected from among a polyaryl sulfide, a polyaryl ether, a polyarylsulfone, a polyarylketone and a polyaryl hexafluoroisopropylidene. A proton conducting solid polymer electrolyte membrane is able to be produced by shaping this proton conducting polymer electrolyte into a film form and crosslinking this proton conducting polymer electrolyte via sulfonic groups.

The present disclosure is directed to conductive, translucent water-borne conductive coatings comprising a water-borne lubricant coating base material, an amount of PEDOT:PSS solution, and an amount of metal-containing nanowire, methods for making the same, and articles coated with such coatings.

Compositions, methods, devices, and systems for purifying a source liquid from a replenishment stock solution that includes stabilizing agents, such as metal ions, prior to vaporization. Certain embodiments effect the purification with a solid perfluoronated ionomer, such as a perfluoronated ionomer membrane. Advantageously, source liquids purified in this manner provide feed stocks for production of ultra-pure gaseous reagents. As well, performance characteristics of membrane-based vaporizers relying on transport processes are improved.
