摘要：
The dielectric properties of polyacrylic acid were studied using dielectric spectroscopy method in the frequency and temperature ranges 0.2 Hz-2 MHz and 2-70 degrees C (at heating), respectively. Thermogravimetric analysis and differential scanning calorimetry were also employed at 25-250 degrees C. A linear dielectric dispersion has been observed at low frequencies. Analysis of electrical modulus showed that the main relaxation process is characterized by non-Debye relaxation time spectrum. The observed anomalies of dielectric properties (conductivity, electrical modulus, dielectric permittivity) are probably related to the presence of water in the sample.
