| Abstract:The application research situation of several cationic natural polymers in papermaking were introduced. Cationization conditions, degree of substitution and application effect of some natural polymers, like guar gum, cellulose, hemicelluloses, and lignin, starch, etc, were analyzed. The cationic natural polymers have more advantages such as cost effective, renewable, environmental friendly, etc, as additive in papermaking. |
