Abstract

The evaluation of oxidation stability of poly(ethylenevinylacetate) (EVA) samples stabilized with rosemary extract under accelerated oxidative degradation by the action of gamma radiation is presented. The FTIR and UV investigations pointed out the efficiency of natural stabilized in the EVA products used for the manufacture of drug packaging, medical wear, blood preservation. The efficiency of additive is spectrophotometrically attributed.
