摘　　要：研究了4,4′偶氮二(4氰基戊酰(对二甲氨基)苯胺)(ACPDA)/过氧化二苯甲酰(BPO)氧化还原引发体系在N,N二甲基甲酰胺(DMF)中引发丙烯酰胺(AAM)的聚合及其动力学行为。考察了聚合反应温度、单体浓度、ACPDA浓度和BPO浓度对聚合反应速率的影响,测定了反应级数和聚合反应的活化能。结果表明,在一定范围内,聚合速率随反应温度的升高、单体浓度的增大、ACPDA浓度的增大和BPO浓度的增大而增大;该体系具有氧化还原引发体系的特点,其聚合速率方程为Rp=K[BPO]0.73[ACPDA]0.54[AAM]1.53,聚合反应的表观活化能为382kJ/mol。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...
