An organic ester suitable as a plasticizer is made from a glycol, a dicarboxylic acid, and an alcohol. The compound can be prepared in the presence of an organic solvent either by a one step route wherein the glycol, carboxylic acid, and alcohol are added together and reacted, or by a two step route wherein first the dicarboxylic acid is reacted with the glycol and the resulting acid ester is subsequently reacted with the alcohol. The end product is suitable as a plasticizer for rubbers such as neoprene wherein it has low volatility and imparts improved peel adhesion.
