Abstract: The results of FT-IR spectral study of polypropylene (PP) subjected to gamma irradiation and postradiation high-temperature shear milling are presented. Absorption peaks of hydroxyl and oxygen-containing groups appear in the IR spectra of air-irradiated PP pellets, the intensity of which decreases markedly in the powder obtained after grinding of irradiated polymer pellets. Toxic properties of PP obtained by grinding by high-temperature shear milling of irradiated polymer pellets were investigated. It was shown that gamma-irradiation of polymer pellets in air has no effect on toxic properties of its powder obtained by grinding of irradiated pellets with 700–4500 kGy dose. It was found that when administered intragastrically to BDF mice1 PP powder from non-irradiated and irradiated granules is moderately toxic.
