Polyeletrolyte complex formations between two oppositely charged polyions[ionene, poly(vinylbenzyl trimethylammonium chloride), poly(diallyl dimethylammonium chloride), polyaminesulfone, potassium poly(vinyl sulfate), sodium poly(stylene sulfonate), poly(acrylic acid)] have been investigated by conductance and trubidity measurements. It was found that the complex formation of these polyelectrolytes formed in stoichiometry. Adsorption isotherms of water, methanol, acetone, and benzene were determined for the resulting complexes at 25°C with a gravimetric adsorption apparatus. The differences in adsorption can be exclusively ascribed to differences in ion site and hydrophobic circumstances around the ion site, since each complex has a low specific surface area (<1 m 2 /g). Amount of adsorption increased in the order of water > methanol > acetone > benzene. This order corresponds to that of the polarity of adsorbate.
