Mono‐ and diesters of fatty acid‐ and aromatic acid‐derived N,N‐disubstituted amides were prepared in which the acid moieties were alternately substituted to function as the basic amide moiety or the terminal ester moiety. Several of the esteramides were evaluated as plasticizers for polyvinyl chloride (PVC). The plasticized stocks exhibited properties that equaled, and in some instances were superior to PVC plasticized with the common plasticizer, di‐2‐ethylhexyl phthalate (DOP). The monoesters were more compatible than the diesters. Thermal stability was enhanced by the presence of the benzoic acid moiety in the molecule. Brittle point temperatures were shown to be a predictable characteristic for specific terminal groups, based on structural similarity of the basic molecule.
