Four divinyl sulfone‐eleostearate adducts were synthesized and compared with dibutyl sebacate as plastieizers for nitrile rubber. Three of these, the adducts of methyl alpha ‐eleostearate, its hydrogenated derivative, and that of tung oil, were found to be satisfactory primary plastieizers. The stocks prepared from the unhydrogenated adducts were superior in plasticizing efficiency to those prepared from their hydrogenated derivatives. The divinyl sulfone‐tung oil adduct yielded a rubber which met the low‐temperature flexibility requirements (−40°C.) of the automotive industry.
