Abstract
A composition comprised of a component selected from the group consisting of a biobased bis-alkyl succinate and a biobased bis-alkyl sebacate, each derived, for example, from the esterification of biobased diacid such as succinic acid or sebacic acid, and a biobased alcohol and a biobased polyester.
