This contribution deals with application of several techniques based on charge transient contactless measurements (isothermal charge transient spectroscopy - IQTS); and by electrochemical methods of double step voltcoulometry and cyclic voltammetry; two complementary methods; which are potentially suitable for obtaining information about bulk relaxation and transport processes and the structure of electronic localized states and their basic parameters. Both methods were tested by two well known polymers; the first; Poly[methylphenylsilylene] and the second Poly(p-phenylene vinylene. The results were explained both in terms of bulk relaxation ant transport processes; trap parameters and the influence of UV degradation. The metastability in reconstruction of dangling bonds ensuing after the UV degradation due to the Si-Si s conjugated bond scission and its ability to reconstruct after the thermal anneal was again found in accord with the previous results.
