Abstract Experimental data of the ac conductivity in polymers and other disordered materials are discussed in terms of theoretical models, especially with respect to a common universal behaviour, as proposed by Summerfield. Two parameters can be extracted from such an analysis, the frequency exponents=0.69±0.04, describing the behaviour at higher frequencies, and a model dependent factorA, ranging between 10−2 and 10−5, that characterizes the crossover from frequency independent values to an ac conductivity increasing with frequency like ω5.
