With the aim of improving the anti-aging properties of nitrile-butadiene rubber (NBR), a functional organic filler, namely LDH⁻SAS, prepared by intercalating 4-amino-benzenesulfonic acid monosodium salt (SAS) into layered double hydroxides (LDHs) through anion exchange, was added to nitrile-butadiene rubber (NBR)
Continuous administration of neozone D to dogs and rats failed to reveal its carcinogenicity. Nor did the agent potentiate the carcinogenic effect of 2-naphthylamine and benzidine in rats. Conversely, neozone D was found to inhibit benzidine-induced carcinogenesis in female rats.
