実験手順

Glycerol (0.2 mol) was added to 30 ml of toluene containing sebacic acid (0.2 mol) dissolved therein, and then stirred in an argon atmosphere at 55° C. for one hour. After an enzyme B (5 wt %) was added as a catalyst, the mixture was allowed to react at 100° C. for 72 hours. Polycondensation was carried out using a dean-stark trap device. The resulting product was dried for 24 hours at reduced pressure.
