Abstract
In this paper piezoelectric studies are described with the films of polyimine derivatives which are presumed to have a preferential orientation of dipole groups in the molecular chains if they are extended and poled. The film of polyimine derived from isophthalaldehyde and 3, 3'-thiodipropionic acid dihydrazide showed quite high piezoelectric constant 0.67×10-7 cgs esu. The results of dynamic modulus and pyroelectric coefficient measurements are also described.
