wherein the polyester comprises (i) monomer units derived from a sugar-based bicyclic diol; (ii) monomer units derived from an unsaturated aliphatic diacid; and (iii) monomer units derived from a saturated aliphatic diacid;

wherein the sugar-based bicyclic diol comprises a bicyclic diacetalized hexitol; and

wherein the monomer units derived from the unsaturated aliphatic diacid are present in an amount of from greater than 0 mole % to 40 mole % of the polyester.
