Abstract The lipase‐catalyzed regioselective polymerization of divinyl sebacate and triols has been carried out. Immobilized lipase derived from Candida antarctica induces the polymerization of divinyl sebacate and glycerol, yielding a soluble polymer of relatively high molecular weight. NMR analysis showed that 1,3‐diglyceride is a main unit and the branching unit (triglyceride) is contained in the resulting polymer. These data indicate that the polymerization proceeds regioselectively to give the reactive polyester having a pendant hydroxy group.
