Abstract
A process for manufacturing polymers of glycerin and hydroxyl fatty acids, for example, polyglycerol polyricinoleates, which mix a polyglycerol with a hydroxyl fatty acid directly to form a reaction mixture, and then heat the reaction mixture to a temperature sufficient to cause it to polymerize through an esterification mechanism until the reaction mixture reaches a desired acid value.
