Abstract: | The kinetics of accumulation of carbonyl groups in films of polyethylene and polypropylene, subjected to tensile stress during accelerated aging at various temperatures, have been investigated. Stabilized and unstabilized polymers have been used. An inhibition effect at a tensile loading of 20% of the maximum tensile strength was established. |
