Resumen
In this paper we describe the kinetics of oxygen consumption of films of non-vulcanised EPDM rubber irradiated with UV light. Purified rubber shows a lower consumption rate compared with crude rubber. Also, a strong lowering of the rate is observed on irradiating at 365 nm compared with 313 nm. Introduction of benzophenone as initiator increases the rate on irradiating at 365 nm. These results are interpreted in terms of impurity initiated photo-degradation. Use of a hindered amine additive decreases the overall rate of oxygen consumption in proportion to its concentation in the films, thus acting as a stabiliser for this rubber. This stabilising effect is also observed when benzophenone is present in the film. © 1988. 21 3 277 283 Imoto, THE PEROXIDE OF EPDM AND EPM IN THE PRESENCE OF C=C UNSATURATED ORGANIC COMPOUNDS (II) (1970) NIPPON GOMU KYOKAISHI, 43, p. 29 Baldwin, VerStrate, Polyolefin Elastomers Based on Ethylene and Propylene (1972) Rubber Chemistry and Technology, 45, p. 709 Dunn, (1966) J.
