Polymer electrolyte, half cell for electrochemical measurements, and the use thereof

摘要

A polymer electrolyte for an electrochemical half cell, in particular for a reference half cell, contains a polymer which as a first monomer component contains at least one alkyl methacrylate. The alkyl methacrylate has a substituted alkyl group with from three to seven carbon atoms and at least two substitutents. The aforementioned substitutents are selected from the group comprising OR₁ and NR₂R₃, in which R₁, R₂ and R₃ are selected from the group comprising hydrogen, methyl, and ethyl, on the condition that the substituted alkyl group contains the substitutent OH at most once.
