Abstract

The comparative behavior of low-density polyethylene, polypropylene and ethylene-propylene diene rubber subjected to -irradiation is presented for technological purposes in radiation processing. The investigation by nonisothermal chemiluminescence, FTIR-ATR spectroscopy and electrical conductivity were accomplished on SiO2 nanoparticle composites loaded with 2 and 5 wt% filler. The differences between studied polyolefins spring from the unlike configurations, which contain various proportion of tertiary and quaternary carbon atoms. The two concentrations of silica nanoparticles change adequately the material behavior under -radiation..
