Abstract
The binding behavior of sodium dodecyl sulfate (SDS) to quater-nary ammonium substituted hydroxyethylcellulose (cationic cellu-lose) of varying degree of substitution was studied by the following measurements: binding isotherms of SDS to cationic cellulose, dye solubilization of the cationic cellulose/SDS complex, partial molal volume of each cationic cellulose, and spin-lattice relaxation time of SDS protons in the course of binding. Binding isotherms showed features similar to that observed for the globular protein/SDS system. The molecular processes of complex formation between cationic cellulose and SDS is discussed based on these results.
