Abstract
Aliphatic polyesters may be substituted at the alpha- and beta-positions. These aliphatic polyesters may have increased thermal, chemical and hydrolytic stability compared to conventional aliphatic polyesters. In addition, these aliphatic polyesters may be used as high performance lubricants, including lubricants for hard disk drives.
