Abstract

The introduction of stabilizing antioxidants into polymers gives polymer compositions a number of valuable properties and their production and practical application become important. It is possible for these polymer materials to oxidize under the influence of sunlight. In this article, AO-3 brand stabilizer antioxidant modified different PY-342 and F-0220 S polyethylene brands and studied their properties such as thermal stability and thermal oxidation.
