Abstract
PURPOSE: To prepare a homogeneous, low viscosity and soft powdery mercerized carboxymethylcellulose useful as coating materials, etc., by kneading a carboxymethylcellulose together with hydrogen peroxide in a concentrated aqueous caustic alkali solution at a specific temperature.
CONSTITUTION: A homogeneous, low viscosity and soft powdery mercerized carboxymethylcellulose is prepared by dissolving a carboxymethylcellulose in 30W70 wt.% aqueous caustic alkali, adding hydrogen peroxide to the solution and kneading the mixture at 10W60°C. The viscosity of the aqueous solution of the carboxymethylcellulose is 90cps before the initiation of the reaction and decreases to 7cps after the reaction for about 40min. (opencircles). In the ordinary marcerization without hydrogen peroxide, the decrease of the viscosity requires an aging time of ≥100 times compared with this invention (solid circles). The product can be further etherized.
