摘要：
The effect of modification of plasticizer and stabilizer systems on the radiation resistance of flexible PVC compositions for medical applications was studied. Samples were irradiated in a linear accelerator LAE 13/9 of electrons beam with dose of 25 kGy. Biological-chemical and mechanical-physical property data were measured for irradiated and additionally ageing plasticized PVC compositions of modified formulations and compared with those of standard medical grade compositions. Post-irradiated stability of flexible PVC meeting the Pharmacopoeia requirements has been achieved.
