A~tract--The aqueous polymerization of acrylamide initiated by ammonium persulphate/thiolactic acid has been studied at 35 + 0.2 Β° in nitrogen. The rate is given by k[M] 1"4 [thiolactic acid] Β°'24 [ammonium persulphate] ~, where x is nearly 0.5 and 1.0 at concentrations 0.15molel-' and 0,05 mole 1-~
The polymerization of acrylamide (AAm) initiated by redox pair: the ceric ammonium nitrate[Ce(IV)]-hydroxy containing thermolabile azo compounds (R) has been investigated in aqueous nitric acid at 20Β°C. It was determined that how the rate of polymerization depends on [AAm], [R] (1 or 2) and [Ce(IV)]
The polymerization of acrylamide, initiated by a cerium (IV) [Ce(IV)] ammonium nitrate-methionine redox initiator system, was carried out in an aqueous solution at different reaction conditions. The dependence of molecular weight and polymerization yield on the concentration of Ce(IV), polymerizatio
