Abstract
A membrane for use in chloride-sensitive electrodes, comprises a polymer matrix with at least one electroactive component. The polymer matrix of the membrane contains an epoxy resin with an amino compound as a curing agent. For the purpose of reducing the danger of contamination and improving the useful life of the electrode, the epoxy resin is provided with at least one epoxy resin compatible flexibilizer, and the content of epoxy resin plus added flexibilizer in the electrode membrane amounts to more than 60% by weight, while that of the electroactive component is not more than 35% by weight, and preferably not more than 30% by weight.
