Water‐soluble chitosan with a 50% deacetylation degree was prepared according to the literature. The mixtures of water‐soluble chitosan and poly(acrylic acid) (PAA) in water was studied by various experimental techniques, such as viscometry, potentiometry, and transmittance measurements. The results showed that water‐soluble chitosan may complex with PAA through electrostatic attraction. This polyelectrolyte complex exists steadily at about an equimolar unit composition. © 1996 John Wiley & Sons, Inc.
