Three styrene-butyl acrylate-acrylic acid random copolymers with different proportions of acrylic acid were synthesized by emulsion polymerization. By neutralization
a series of ionomers with different proportions of ions and different metal counterions were prepared. The dielectric properties of the sample so obtained were investigated with a DP- I dielectric spectra detector. It was found that the α and β peaks of the dielectric loss tangent (tg δ) coincided like a single peak and with higher permittivities (εr)
if the unneutralized copolymers were used as the parent materials.As ionization was increasing
