Beschreibung
Zusammenfassung:Disclosed herein are compositions comprising at least one alpha-glucan graft copolymer derivative compound (e.g., ether or ester) having a degree of substitution (DoS) up to about 3.0. The precursors of these derivative compounds are graft copolymers that comprise a dextran backbone and alpha-glucan side chains. At least about 30% of the glycosidic linkages of the alpha-glucan side chains are alpha-1,3 glycosidic linkages. Further disclosed are methods of producing graft copolymer derivatives, as well as their use in various applications and products.
