Reaction Conditions

Reaction Steps

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 was 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 to 160 to 210° C. and water taken off until the batch gelled. Gelation began to occur after about 134 g of the water was collected. The 134 g of water collected was 77% of the theoretical amount. Depending upon the level of post-gelation heating, the product had a consistency ranging from a sticky gum containing about 15% by weight of a water-soluble fraction to that of a somewhat hard glass with a water-soluble fraction of 1% or less.
