Lipase-catalyzed synthesis and characterization of polymers by cyclodextrin as support architecture

► Aliphatic polyesters are synthesized by enzymatic lipase catalysis, without using solvents. ► Lipase from Candida sp. initiates the polymerization. ► β-Cyclodextrin safeguards the polymer chain from coagulation. ► High molecular weight polyesters (62,100 Da) are obtained in a three-stage reaction. ► Polymers are stable till 350 °C, with a 72% crystallinity, thus improving the storage modulus.
