Zusammenfassung:The disclosure relates to polysaccharide derivatives comprising a polysaccharide substituted with at least one carbamate group, wherein the polysaccharide comprises poly alpha-1,3-glucan, poly alpha-1,3-1,6-glucan, or a mixture thereof, and the polysaccharide derivative has a degree of substitution of about 0.001 to about 3 with the carbamate group. The disclosure further relates to compositions comprising the polysaccharide derivative, and to a fiber, film, coating, or article comprising the polysaccharide derivative. L'invention concerne des dérivés de polysaccharide comprenant un polysaccharide substitué par au moins un groupe carbamate, le polysaccharide comprenant du poly-alpha-1,3-glucane, du poly-alpha-1,3-1,6-glucane, ou un mélange de ceux-ci, et le dérivé de polysaccharide ayant un degré de substitution d'environ 0,001 à environ 3 avec le groupe carbamate. L'invention concerne en outre des compositions comprenant le dérivé de polysaccharide, et une fibre, un film, un revêtement ou un article comprenant le dérivé de polysaccharide.
