Description
Summary:A levulinoyl ester‐containing cellulose polymer is introduced as a waterborne coating. Incorporation of the biomass‐derived levulinic acid proceeds via an unexpected intermediate and provides the unusual feature of a cellulose derivative that is readily chemically modified. The levulinoyl‐cellulose ester could be chemically manipulated, allowing it to be dispersed to generate a waterborne hydrocolloid latex. This was capable of film‐formation at room temperature, and was formulated for use as a coating of high‐renewable content. Pulp Nonfiction: Wood pulp modified with cellulose‐derived levulinic acid generates a “doubly‐renewable” biopolymer—with >75 % renewable content—for industrial applications. The process is scalable and the polymer may be modified to improve its physical characteristics. The utility of this biobased polymer is demonstrated by the production of a novel coating formulation.
