Effect of Molecular Weight of Poly-N-benzyl-N,N-dimethyl-N-methacryloyloxyethylammonium Chloride on Its Complexation with Sodium Dodecyl Sulfate

摘要

Complexation of a cationic polyelectrolyte, poly-N-benzyl-N,N-dimethyl-N-methacryloyloxyethyl-ammonium chloride, with an anionic surfactant, sodium dodecyl sulfate, in aqueous solutions is studied. The effect of the molecular weight of the polymer on phase separation in the system and on the stability, conformation, and surface activity of the polyelectrolyte-surfactant complexes is examined.
