Abstract

Water soluble poly(sulfonated styrene-co-acrylic acid) was polymerized with sulfonated styrene and acrylic acid in the presence of silver sulfate at $99^{\circ}C$ for 4 hrs. The complex formation of poly(sulfonated styrene-co-acrylic acid) with Cu(II) was carried out. The maximum absorption wavelength of the poly(sulfonated styrene-co-acrylic)-Cu(II) system at different pH values was observed at 274 nm and 295 nm. The reduced viscosity of the poly(sulfonated styrene-co-acrylic acid)-Cu(II) complex were measured in the various pH ranges. The formation constants and stability constants of poly(sulfonated styrene-co-acrylic acid)-Cu(II) complex were calculated from Bjerrum method. The changes of enthalpy, free energy and entropy in the above reaction were determined by Ringbom method.
