Beschreibung
Zusammenfassung:	Compositions are disclosed herein comprising a graft copolymer that comprises: (i) a backbone comprising an alpha-1,3-glucan ether or ester compound, and (ii) one or more alpha-1,3-glucan side chains comprising at least about 50% alpha-1,3 glycosidic linkages. Further disclosed are reactions for producing such graft copolymers, as well as their use in various applications. L'invention concerne des compositions comprenant un copolymère greffé qui comprend : (I) une chaîne principale comprenant un composé éther ou ester d'alpha-1,3-glucane, et (ii) une ou plusieurs chaînes latérales d'alpha-1,3-glucane comprenant au moins environ 50 % de liaisons glycosidiques alpha-1,3. L'invention concerne également des réactions de production desdits copolymères greffés, ainsi que leur utilisation dans diverses applications.
