The dielectric properties of poly(hexylisocyanate) solutions in electric fields

Abstract The effect of large electric fields (≤0.8 MV m −1 ) on solutions of poly(n-hexylisocyanates) of differing molecular weights is described. Non-linear dielectric effects are observed and their magnitudes are in fair agreement with those predicted theoretically for inflexible dipolar molecules of low polarizability. Small enhancements of relaxation frequencies are also caused by the application of large electric fields.
