    Patent number: 7799465
    Abstract: There is described a fuel cell or electrolytic cell comprising an ion-conductive polymeric material which includes a first repeat unit of formula (I): —(O-Ph1-CO-Ph1-O-Ph1-CO-Ph1)-, and a second repeat unit of formula (II): —(O-Ph2-O-Ph3-CO-Ph4)-, or of formula (III): (O-Ph2-O-Ph3-SO2-Ph4)-; wherein Ph1, Ph2, Ph3 and Ph4 independently represent phenyl moieties and wherein said second repeat unit is provided with ion-exchange sites. The polymeric material may include a third repeat unit which is amorphous.

  • POLYMERIC MATERIALS
    Publication number: 20100076114
    Abstract: An assembly comprises first and second parts which bear against one another, wherein said first part comprises a polyetherketone and said second part comprises a polyetherketone. The parts bear against one another such that one or both of the parts may have a tendency to wear and/or produce wear debris by virtue of contact between the parts. The materials used, however, minimise wear and the production of such wear debris.

  • Polyketones
    Patent number: 7160980
    Abstract: Method of purifying a polymeric material of a type which includes (A) phenyl moieties; (B) carbonyl and/or sulphone moieties; and; (C) ether and/or thioether moieties. The method includes contacting the polymeric material with a solvent formulation which is at a temperature of greater than 100° C. and a pressure above ambient pressure thereby to charge the solvent formulation with impurities derived from the polymeric material, and separating the charged solvent from the polymeric material.
