PROBLEM TO BE SOLVED: To provide a simple method for producing aliphatic polyesters including a biodegradable polymer at a low cost in a short time in a high yield. SOLUTION: The method for producing aliphatic polyesters comprises subjecting aliphatic polyols and aliphatic dicarboxylic acids to polycondensation reaction by microwave heating. The microwave heating is preferably performed by microwave irradiation with an output of 30-1,500 W. This polycondensation reaction is preferably carried out in the presence of a catalyst, and above all, the use of an organometallic compound catalyst is preferred. COPYRIGHT: (C)2006,JPO&NCIPI
