Abstract
A new method to investigate the temporal stability of electric field poling induced polarization in polymers using piezoelectric effect is described. The results of two PMMA-based side chain copolymers are presented. A comparison with the results of Second Harmonic Generation (SHG) experiments is given. Glass transition ranges for the polymers were determined by thermal dependent SHG experiments.
