Procedure

To a 1-liter heated resin kettle equipped with agitator, thermometer, and condenser with distillation head, 294 g (9.64 equivalents) of glycerol was added. The glycerol was agitated and heated to about 100° C., and 704 g (9.64 equivalents) of adipic acid was added. After all the adipic acid was added, the batch was heated to 150-200° C. and water taken off at atmospheric pressure. Water began to distill when the temperature of the reaction mixture reached 150 to 160° C. The batch was heated further heated to 160 to 210° C., and water collected until a total of 110 g was obtained. The 110 g of water collected was 63% of the theoretical amount.
