A new family of sulfur-containing plasticizers derived from fatty acids has been developed. The synthetic approach is based on the thiol–ene addition of alkyl thiols to the double bond of technical oleic acid, followed by oxidation of the sulfide group to either sulfoxide or sulfone groups. It has been found that both sulfide and sulfoxide derivatives are not suitable as plasticizers due to their unpleasant
