Abstract:
1. A cellulose derivative, comprising A) a hydrocarbon group; B) a group containing an acyl group: —CO—R C) an acyl group: —CO—R wherein the carboxyl group included in the cellulose derivative is in an amount of 0.5% by mass or less, based on the cellulose derivative, wherein each of A), B) and C) is independently contained in the cellulose derivative, and wherein the cellulose derivative has degrees of substitution of 1.0<DSa<2.5, 0<DSb and 0.1<DSc<2.0 wherein DSa is the degree of substitution of the hydrocarbon group A) with respect to the hydroxyl groups at the 2-, 3- and 6-positions of a β-glucose ring in a repeating unit, DSb is the degree of substitution of the group containing an acyl group and an ethyleneoxy group B) with respect to the hydroxyl groups at the 2-, 3- and 6-positions of a cellulose structure of a β-glucose ring in a repeating unit and DSc is the degree of substitution of the acyl group C) with respect to the hydroxyl groups at the 2-, 3- and 6-positions of a cellulose structure of a β-glucose ring in a repeating unit.
