A number of N‐acyl derivatives of bis(2‐alkoxyethyl) amines have been prepared, characterized and screened as plasticizers for poly (vinyl chloride‐vinyl acetate) copolymer. Included were the N,N‐bis (2‐alkoxyethyl) amides of saturated (normal and branched), unsaturated, epoxy, dimer, terpenic and naphthenic acids as well as mixed acids from animal fats, rapeseed, Limnanthes douglasii seed, parsley seed and selectively hydrogenated cottonseed oils. With the exception of the linoleic acid derivative, all these amides, including the stearamide derivative, were compatible. Some exhibited low‐temp properties comparable to the adipate plasticizers without the adverse volatility characteristics of the adipates. With the exception of the epoxystearamide derivative the N,N‐bis(2‐alkoxyethyl)amides were inferior to dioctyl phthalate in thermal stability. The N,N‐bis(2‐ethoxyethyl)stearamide is of special significance in that it seems to be the only carboxylic derivative of stearic acid known to be effective as a primary plasticizer.
