Аннотация:The dielectric response and alternating current conductivity for poly(methyl methacrylate) - polyimide (PMMA-PI) system with different portions of initial components are calculated. The measurements have been done at the frequencies 20 Hz-20 kHz and temperatures -50-50°C. It was shown that the relaxation spectra in PMMA-PI copolymer are determined by the relaxation of PI even for the PMMA : PI system with weight ratio 96:4 respectively. The results presented suggest that alternating current conductivity of such systems is very small and decreases with increasing of PI portion in PMMA/PI copolymer.
