Summary Eight derivatives of tung oil, namely, the methyl vinyl ketone, dimethyl maleate, methyl acrylate, and acrylonitrile adducts, and their hydrogenated products, were prepared and screened as softeners for Buna‐N rubber with dibutyl sebacate, as the control. Five of the eight products evaluated yielded stocks that met the low‐temperature flexibility requirements (−40°C.) of the automotive industry. In all cases the stocks prepared from the unhydrogenated derivatives were superior in plasticizing efficiency to the stocks prepared from their hydrogenated counterparts or to those prepared from the control.
