The behavior of cellulose materials in aqueous solutions of polyethylenimine was investigated. Sulfite‐bleached cellulose, sulfite unbleached, sulfate unbleached, and monocarboxylcellulose were used. The adsorption kinetics of polyethylenimine by monocarboxylcellulose were studied in detail. The velocity constants of the process, the velocity temperature coefficients, and the activation energies were calculated. The reaction order was established. The physical type of polyethylenimine adsorption by cellulose was established, and it was shown that the adsorption isotherms comply with the equation of Langmuir. On the basis of the data and on the dependencies obtained, the equations of adsorption in the temperature interval of 0°C to 60°C were derived.
