The Mechanism of Radiation Damage to Elastomers. I. Chain Scission and Antirad Action

Richard G. Bauman, John W. Born

Open publisher page 1 citations

Abstract

Abstract The effect of antirads on chain scission as measured by stress relaxation is one of inhibition both in the presence of air and to a lesser extent in its absence. This can be explained by assuming a reactivity of the antirads with RO2⋅ radicals yielding stable products, and a somewhat decreased reactivity with R⋅ radicals. A greater tendency of RO2⋅ radicals to lead to chain scission than R⋅ radicals seems to be indicated.
