Abstract
Provided herein are polyesters that comprise (i) monomer units derived from sugar-based bicyclic diol; (ii) monomer units derived from an unsaturated aliphatic diacid; and (iii) monomer units derived from a saturated aliphatic diacid. The monomer units derived from the ethylenically unsaturated aliphatic diacid can be present in an amount of from greater than 0 mole % to 40 mole % of the polyester. These polyesters can be formed into articles using additive manufacturing methods. The resulting articles can be biocompatible, resorbable over a span of from 3 months to 12 months following implantation in the human body, and can exhibit desirable mechanical properties for applications, including porosity and elasticity.
