Annotation	Viscoelastic properties of cellular polypropylene ferroelectrets (PP FEs) were studied at low frequencies (0.3-33Hz) by dynamic mechanical analysis and at high frequencies (250 kHz) by laser Doppler vibrometry. Switching-off the relaxation contribution causes dynamic crossover from the nonlinear viscoelastic regime at low frequencies to the linear viscoelastic regime at high frequencies.
