The kinetics of acrylamide(AAM) polymerization initiated by 4,4'-azobis-(4-cyanopentanoyl(p-dimethylamino)anilide)(ACPDA)/dibenzoyl peroxide(BPO) redox system was studied in N,N-dimethylformamide. The effects of concentrations of the monomer, ACPDA, BPO and the temperature on the polymerization rate were studied. The reaction order and the activation energy were determined. The results indicate that the polymerization rate increases with increasing the concentrations of monomer, ACPDA, BPO as well as the reaction temperature. The system has the characteristic of a redox initiation system. The equation of the polymerization rate is R_p=K[BPO]^0.73[ACPDA]^0.54[AAM]^1.53 with an apparent activation energy of 38.2 kJ/mol for AAM polymerization.
