Patent number: 8648155
Abstract: The present description discloses a polymeric composition which is a melt-processed alloy comprised of (a) a polyarylene sulfide resin, (b) a polyaryl-ether-ketone resin, and a reactive compound which results in (c) a graft copolymer of the polyarylene sulfide resin and/or the polyaryl-ether-ketone resin in addition to the starting resins. Exemplary melt-processed polymeric compositions can be made by reacting an alkoxy silane with the polyarylene sulfide resin and/or the polyaryl-ether-ketone resin to produce a graft copolymer of a portion of one or both of the resins, sufficient to render the composition uniform and homogeneous. It is normally preferred for the exemplary organosilane compound, to be an amino silane. The subject invention further reveals an insulated wire comprising (1) an electrical conductor and (2) a layer of the melt-processed alloy composition; and fiber reinforced composites comprising fibers substantially fully impregnated with the alloy polymeric composition.

Patent number: 8383756
Abstract: A composition of matter for the recording medium of nanometer scale thermo-mechanical information storage devices and a nanometer scale thermo-mechanical information storage device. The composition includes: one or more polyaryletherketone copolymers, each of the one or more polyaryletherketone copolymers comprising (a) a first monomer including an aryl ether ketone and (b) a second monomer including an aryl ether ketone and a first phenylethynyl moiety, each of the one or more polyaryletherketone copolymers having two terminal ends, each terminal end having a phenylethynyl moiety the same as or different from the first phenylethynyl moiety. The one or more polyaryletherketone copolymers are thermally cured and the resulting cross-linked polyaryletherketone resin used as the recording layer in an atomic force data storage device.

Patent number: 8349994
Abstract: Disclosed is an electrode electrolyte for solid polymer fuel cells, which uses a polymer electrolyte containing a polyarylene copolymer containing a nitrogen-containing aromatic ring having a substituent represented by —SO3H, —(O(CH2)hSO3H or —O(CF2)hSO3H (wherein h represents an integer of 1-12). By having such a constitution, the electrode electrolyte for solid polymer fuel cells can be produced at a low cost, while being excellent in proton conductivity, dimensional stability, hydrothermal resistance and mechanical strength. In addition, this electrode electrolyte for solid polymer fuel cells enables to recover a catalyst metal.
