| 摘 要： | N-[(3-DimetLylamino)-propyll acrylamide(DMAPAA) and N-[(3dimetliylamino)-propyl] methacrylamide(DMAPMA) were synthesized by the reaction of 3-dimethylamino-propylamine with acryloyl and methacryloyl chloride respectively at 0-5℃ temperature. The kinetics of the aqueous solution polylmerization of acrylamide(AAm) by using ammonium persulfate(APS) combined with DMAPAA or DMAPMA was investigated. The rate equations were given as:respectively. The overall activation energies of the polymerization were determined as low as 35.0kJ/mol and 41.0kJ/mol respectively. Based on the end-group analysis results, the reaction mechanism of DMAPAA or DMAPMA with APS was proposed to be similar to the initiation reation of persulfate/tertiary aliphatic amine redox system,and the resulting aminomethyl radicals were responsible for initiation of vinyl polymerization as well as sulfate radical.
