ESTERIFIED POLYSACCHARIDE PRODUCTS AND .GAMMA.-LACTONE RING OPENED KETENE DIMER PRODUCTS CONTAINING THE COMPOSITIONS, AND PROCESS OF MAKING THE SAME

摘要

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 .GAMMA.-lactone ring opening alcoholysis of ketene dimers and the process of making such compositions containing products.
