Abstract: 

Water soluble polymers are widely used in various industrial areas. Surface activity is also important for some applications in industry. In this study, a surface-active substance was synthesized by interaction of polyacrylic acid (PAA) with propylene oxide (PO). Polyacrylic acid was synthesized by radical polymerization of acrylic acid (AA) in toluene and under atmosphere of nitrogen. Oxypropylation reaction of PAA was carried out repeatedly for various initial reactant concentration and temperature values in order to investigate the kinetics of the oxypropylation reaction. The probable mechanism of “cooperative” character of oxypropylation reaction of PAA carboxylic groups was proposed on the basis of the obtained experimental data. The obtained compound from the reaction was characterized by a number of physico-chemical methods.
