| Abstract: | The aqueous polymerization of acrylamide initiated by ammonium persulphate/thiolactic acid has been studied at 35 ± 0.2° in nitrogen. The rate is given by k[M]1.4 [thiolactic acid]0.24 [ammonium persulphate]x, where x is nearly 0.5 and 1.0 at concentrations 0.15 mole l?1 and 0.05 mole l?1 of monomer respectively. The deviations from normal kinetics are discussed. The overall activation energy is 7.96 kcal mole?1. |
