Electrophysical properties of poly(methyl methacrylate)-polyimide systems
Source abstract
Abstract
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 20Hz-20kHz and temperatures m 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 inPMMA/PI copolymer.
