Abstrakt: The addition products obtained by the Diels-Alder reaction of acrylonitrile with the methyl, ethyl, and butyl eleostearates have been prepared in good yields and purified by means of high-vacuum distillation. It has been possible to saturate preferentially by hydrogenation both the cyclic and exocyclic double bonds of the acrylonitrile adducts without material reduction of the nitrile group. Also the acrylonitrile adduct of tung oil has been prepared. All these adducts have been intercompared with DOP and evaluated as primary plasticizers for vinyl chloride-vinyl acetate copolymer. These products, with the exception of the nonhydrogenated ethyl and butyl derivatives, were found to be satisfactory as primary plasticizers. The results obtained indicate that hydrogenation greatly improves the compatibility of the adducts without changing their other plasticizing characteristics appreciably. The outstanding characteristic of all the adducts is their high plasticizing efficiency, as reflected by their low modulus at 100% elongation.
