Abstract
The relationship between electric displacement D and electric field E was studied for polyamides consisting of m-xylylenediamine and aliphat ic dicarboxylic acids with numbers of carbon atoms from 6 to 11 and 13 . Regardless of the number of carbon atoms in the acids, quenched samp les of these polyamides exhibit a D-E hysteresis loop with remanent po larization of 23-67 mC.m-2. polarization is related to the amide group s aligned by the electric field.
