A copolymer containing, in addition to recurring elements of a sulfonated poly(arylene) containing exclusively recurring structural element(s) of the general formulas &#x2014;[&#x2014;Ar(SOM)-X&#x2014;]&#x2014; and &#x2014;[&#x2014;Ar(SOM)-Y&#x2014;]&#x2014;, wherein X and Y, which are identical or different from each other, each represent an electron-acceptor group, Arand Ar, which are either identical or different from each other, represent an aromatic or heteroaromatic ring system with 5-18 ring atoms; wherein the aromatic or heteroaromatic ring system, in addition to the SOM and the substituents X and Y, optionally comprises additional substituents which are not electron-donor groups; M represents monovalent cation and n is an integral number between 1 and 4; and wherein X, Y, Ar, Ar, M and n can be identical or different in various structural elements, independently of each other, one or several additional elements of at least one additional monomer or macromonomer.

Sulfonated poly(arylenes), polymer compounds and methods of producing the same

Hydrolytically and thermo-oxidatively stable sulfonated polyarylenes include the structural element &#x2014;X&#x2014;Ar(SOM)-Y&#x2014;. The aromatic ring carrying the sulfonic acid group is substituted exclusively by electron-acceptor bridge groups X and Y and, if applicable, by other non-electron-donor substituents. Their synthesis and application are also included.

The invention relates to a waste water immersion probe () comprising a liquid-tight housing (), a sensor () which is disposed in the housing () and a sensor window () formed on the housing (). A wiper element () for cleaning the sensor window () is arranged on the outside of the sensor window (), and the wiper element () is driven by a drive motor () which is arranged essentially in the housing (). The housing is devoid of openings. A magnetic element () is associated with the drive motor () and a magnetic element () is associated with the wiper element () in such a manner that the magnetic drive motor element () produces a magnetic field which transverses the housing wall and transmits a drive torque to the wiper element () without a shaft.
