Poly(lactic acid)‐block‐poly(oxirane)s (PLA‐b‐POE) of various compositions were prepared using a one‐pot approach and then extended in a reaction with l‐lysine diethyl ester diisocyanate, thereby forming polyester–ether–urethanes (PEU) with prolonged chains and units with increased degradability. The PEUs are processed by electrospinning to prepare degradable nanofibrous sheet materials with and without encapsulating the antibiotic Vancomycin (VAC). PLA block isomerism and POE blocks oligomeric content (1000 g/mol) affect the thermal properties, processability, nanofibrous sheet morphology, abiotic degradation, cytocompatibility, and encapsulated antibiotic release rate of prepared PEUs. Therefore, our findings provide an effective approach to tuning the functional properties of these advanced biocompatible materials.
