Abstract

The thermal pulse technique was used to measure the electric polarization and its distribution in the alternating copolymer of vinylidene cyanide and vinyl acetate P (VDCN-VAc), with poling voltage and poling temperature as variables. The thermal stability of the polarization was evaluated at several ageing temperatures up to the glass transition temperature. The polarization was found to be proportional to the poling field up to 50 MV/m and very stable for ageing temperatures up to 150°C
