Biodegradable polyurethanes are typically prepared from polyester polyols, aliphatic diisocyanates and chain extenders. We have developed a degradable chain extender (DCE) based on DL-lactic acid and ethylene glycol to accelerate hard segment degradation. Three series of polyurethane elastomers were
