Aqueous solution polymerizations of vinyl monomers
such as acrylamide (AAM)
acry-lonitrile (AN) and methyl methacrylate (MMA)
initiated with peroxydisulfate and N
N
N'
N'-tetramethylethylenediamine (TMEDA) system have been investigated in this paper. It was found that when the ratio of [TMEDA] /[peroxydisulfate] was in the range of 0.5-2
the polymerization rate Rp and the ultimate conversion were enhanced while the ultimate conversion decreased when the ratio was 5-50
and the molecular weight of polymer always decrea-sed. The activation energyof polymerization and polymerization rate equation were deter-mined.
