Abstract
This invention relates to a process for making polarized material by forming a solution of a material capable of being polarized with a polarization solvent. The material in solution is poled to provide a polarized material and during the poling the solvent is removed to the extent desired or totally to provide a polarized material which is free or substantially free of mechanically-induced orientation and which polarization is essentially stable up to the crystal melting point of the polar crystals or to softening point of the polarized material if non-crystalline.
