Abstract
The kinetics of the radical polymerization of acrylamide (AA) and alkaline hydrolysis in inverse water-toluene emulsions, in the presence of non-ionic surfactants, hydrolyzing agents (NaOH, Na 2CO 3) and potassium persulphate (PS)-tris-(2-carbamoylethyl)-amine (CA) redox couple at 25–50°, have been investigated. For the overall rate of polymerization, the following expression has been found −[AA] dt=K[AA] 1.37[PS] 0.68[CA] -1.07 The rates of polymerization and hydrolysis increase with increasing NaOH concentration. With increase of the ratio PS/CA and AA concentration, the rate of alkaline hydrolysis and the content of sodium acrylate (NaA) in copolymer are shown to decrease. The possibility of preparing copolymers of AA with NaA of various compositions and molecular weights in the range 0.1 × 10 5-5.6 × 10 6 has been demonstrated.
