Abstract:
1. A method of producing a cationized cellulose, the method comprising: first, adding a cationizing agent represented by formula (1): wherein each of R to a cellulose and mechanically decrystallizing the cellulose with a tank-drive media mill such that a reduction (P reaches 1 to 60%, thereby obtaining a mixture, and second, adding a basic compound to the mixture obtained from said first adding in an amount of 0.01 to 1 equiv per one mole of anhydroglucose unit of the cellulose in the mixture and mechanically decrystallizing the cellulose with a tank-drive media mill such that a reduction (P reaches 1 to 80%, wherein the cellulose is allowed to react with a cationizing agent represented by formula (1) during said second adding.
