Abstract: An electrode electrolyte system is provided that is capable of operating in slope sensors in a wide range of temperatures. The eletrolytic system is characterized by a stable conductivity at high temperature and by low toxicity. The slope sensor can be installed in a system containing an Nal solution in propylene carbonate, combined with platinum electrodes.

Abstract: Anion-exchanging molded bodies and a method of manufacturing the same. The aim is to find anion-exchangers which can be produced in any shape simply, cheaply and reproducibly, without the use of carcinogenic chloromethyl ethers. It has been established that halogenated polyethers, preferably epichlorhydrin polymers, can be treated with tertiary amines together with inert polymers to produce such anion-exchanging molded bodies by a phase-inversion process or evaporation of the solvent. These molded bodies can be in the form of blocks, balls or films.

Abstract: Chloromethylated polymers are generally used to produce strongly alkaline anion exchange membranes. This requires handling toxic chloromethyl ethers. The object of the invention is thus to create anion exchange membrane which is easy and cheap to produce in a reproducible manner and has good electrochemical properties. It has been discovered that halogenated polyethers, preferably epichlorohydrin polymers with tertiary amines together with an inert polymer may be shaped into such membranes having a high mechanical stability. These membranes may be designed as anion exchange membranes for electrodialytical desalination as acid blocker anion exchange membranes for electrodialysis of acid solutions or as large pore membranes for the transport of large anions.
