Cationic dextran polymer derivatives including an ester-linked amine-containing substituent and an alkyl ester substituent the ester-linked amine-containing substituent being selected from Formula (I) and methods for making such dextran polymer derivatives are disclosed. And mixtures thereof, wherein R 1 is selected from C 1 to C 4 alkyl groups, R 2 and R 3 may be the same or different and are selected from hydrogen, methyl and ethyl groups, and R 4, R 5, and R 6 may be the same or different and are selected from methyl and ethyl groups, and wherein the degree of substitution of said ester-linked amine-containing substituent is at least 0.03; and the alkyl ester substituent being selected from acetate, propionate, butyrate, isobutyrate, and mixtures thereof, wherein the degree of substitution of said alkyl ester substituent is at least 0.05. |
