  • Patent number: 11505682
    Abstract: Molded articles are disclosed herein, the molded article comprising a polysaccharide, wherein the polysaccharide comprises i) poly alpha-1,3-glucan; ii) poly alpha-1,3-1,6-glucan; iii) a graft copolymer that comprises (A) a backbone comprising dextran with a weight-average molecular weight (Mw) of at least about 100000 Daltons, and (B) poly alpha-1,3-glucan side chains comprising at least about 95% alpha-1,3-glucosidic linkages; or iv) a composition comprising a poly alpha-1,3-glucan ester compound as disclosed herein. Optionally, the molded articles can further comprise a plasticizer and/or starch. The molded articles can be useful as a container, a handle, packaging, a tray, a bottle, a cup, a sheet, a disposable food packaging item, an automotive part, a casing for an electronic device, or a toy.
