摘要：
To follow gamma-irradiation effect upon PEO crystalline structure WAXS and SAXS investigations have been carried out. Thermal treated samples are prepared. Experimentally obtained data show that under irradiation with doses over 10 Mrad amorphous regions are mainly changed. Effect of radiation annealing and perfection of the crystalline structure is observed. Radiation with doses over 10 Mrad causes partial amorphization of crystallites and effect of radiation melting. A packing of the lamellar aggregates and increasing of the porous size are observed.
