| Popis: |
The polarization phenomena of the polybutadiene - acrylonitrile (PBAN) copolymers have been investigated in the vicinity of the glass transition region by methods of thermally stimulated depolarization currents (TSDC), thermally stimulated polarization currents (TSPC) and dc conductivity. Relaxation regions above the glass transition temperature Tg have been analyzed by thermal sampling and partial depolarization techniques in more detail. The effects associated with the cyclizing after pyrolysis in PBAN copolymers have been studied by thermally stimulated and viscoelastic measurements. |
