D.F. is grateful to the Universidad Autónoma Metropolitana-Iztapalapa, Mexico City, for the guest professorship in the frame of the Cathedra “Alonso Fernandez.” The project was supported by the Grant Agency of the Czech Republic – Czechia ( P108-12G-108 ) and the Nuclear Physics Institute – Czechia, Řež near Prague. We are further obliged to Dr. P. Apel from JINR Dubna, Russia for providing us with most of the examined ion-irradiated polymer foils over the past two decades, and for giving us highly valuable hints during the preparation of this manuscript. Thanks also to Dr. Trautmann from GSI and Prof. G.Szenes from Eoetvoes University for providing many of the other samples. Further, we want to express our thanks to the former (1995-2005) HMI accelerator team for enabling us to perform quite a number of own SHI sample irradiations at the former HMI Berlin. We also want to thank Mrs. S. Vacik for proofreading. Finally, we wish to acknowledge the excellent work of the anonymous reviewer which helped much to improve the quality of that paper and for which we are therefore very grateful.

N2 - Some yet poorly understood problems of etching of pristine and swift heavy ion track-irradiated aged polymers were treated, by applying conductometry across the irradiated foils during etching. The onset times of etchant penetration across pristine foils, and the onset times of the different etched track regimes in irradiated foils were determined for polymers of various proveniences, fluences and ages, as well as their corresponding etching speeds. From the results, correlations of the parameters with each other were deduced. The normalization of these parameters enables one to compare irradiated polymer foils of different origin and treatment with one another. In a number of cases, also polymeric gel formation and swelling occur which influence the track etching behaviour. The polymer degradation during aging influences the track etching parameters, which differ from each other on both sides of the foils. With increasing sample age, these differences increase.
