Polyelectrolyte complex based on chitosan and acrylic acid monomers by photoinitiated free radical polymerization in the absence of crosslinker showed a large transition in swelling in response to changes in pH of surrounding medium.Their ability to swell arises from polyelectrolyte interactions and molecular structure of the complex. The main properties of interest that related to the molecular structure, swelling volumes and elastic moduli of the complex have been investigated.The effect of water (diluent), the only variable in sample component played an important role in molecular structure of the complex and as a consequence, the extent of intermolecular linkage, especially amide bonds which in turn governed the degree of swelling of the polyelectrolyte complex in this study.The increased modulus of elasticity at dry state was found in lower water (diluent) content and increased degree of swelling was found in higher water (diluent) content of the complex.
