✦ Synopsis


The kinetics of aqueous polymerization of acrylamide (AM) and methacrylamide (MAM) have been studied using a potassium peroxydiphosphate (PDP/Mn(II) system in an inert atmosphere at 40¡C and at constant pH (1É30). The polymerization rate has been found to be proportional to the half power R p of PDP and Mn(II) concentrations. The overall energy of activation (*E) was found to be 40É2 ^0É1 kJ mol~1 and 45É0 ^0.1 kJ mol~1 for AM and MAM, respectively. Intrinsic viscosity [g], viscometric average molecular weight (M 1 v ) and number average degree of polymerization at di †erent concentrations of (P1 n ) PDP, Mn(II) and monomer are reported.
