Polarized products and processes

摘要

This invention relates to a polarized material which has polarization which is essentially stable up to the crystal melting temperature range of the polar crystals or to the softening temperature range or the glass transition temperature range of the polarized material if it is non-crystalline. A preferred polarized material provided is poly(vinylidene fluoride), blends of poly(vinylidene fluoride) and vinylidene copolymer and blends of odd Nylons such as Nylon-7 and Nylon-11.
