Abstract
Product of esterified polysaccharides and the process of making such product. The process can be enzymatic where an enzyme is used as a catalyst for the reaction. The process can also be chemical where no enzyme is used. Novel products are obtained through lipase-catalyzed &bgr;-lactone ring opening alcoholysis of ketene dimers and the process of making such compositions containing products.
