The one‐pot biocatalytic synthesis of amphiphilic polymers consisting of an isosorbide headgroup and a hydrophobic polyester chain is described. The immobilized lipase of Yarrowia lipolytica (YLL) catalyzed ring‐opening polymerization of ε ‐caprolactone ( ε ‐CL) initiated by the multifunctional initiator isosorbide. Polymerizations were carried out in bulk at 70, 80, 90 and 120 °C. The highest reaction rates for ε ‐CL polymerization resulted for YLL immobilized on macroporous resins: Lewatit VP OC 1026 at 80 °C, and the strongly acidic Lewatit K‐2629 at 90 °C. Structural analyses were made by MALDI‐TOF, 1 H, and 13 C‐NMR.
