Abstract: Copolymers comprising cellulose and starch connected by at least one cross-linker, methods of producing the copolymers, and formed articles comprising the copolymers are described herein. The copolymers may be biodegradable and may have improved physical properties when compared to the homopolymers and other biodegradable polymers. In some embodiments, the copolymer may be more flexible than unmodified cellulose may have better structural integrity than unmodified starch.
