Abstract
NR and BR vulcanizates of sulfur accelerated with DPG or MBT, of TMTD and of Di-Cup were prepared. Peroxide vulcanization was carried out for comparison with sulfur-containing crosslinks. Effect of the nature of crosslinks on the radiation deterioration of vulcanizates was investigated by determining the cross-linking densities before and after irradiation. The results obtained are summarized : (1) sulfurcontaining crosslink has higher resistance to irradiation than C-C crosslink and (2) polysulfide link is more resistant than monosulfide one.
