The kinetic laws of polymerization of sodium 2-acrylamido-2-methylpropanesu
lfonate carried out at pH 9 and 60 degrees C in the inverse water-heptane e
mulsions in the presence of emulsifier (sorbitan C) and water-soluble initi
ating system (potassium persulfate-sodium bisulfite) were studied by dilato
metry. It was shown that the kinetics of the process under study is similar
to the kinetics of solution polymerization. It was demonstrated that the i
nitial rate of polymerization and the molecular mass of the polymer change
in a cymbate manner with an increase in the emulsifier concentration. The k
inetic curves show maxima when the emulsifier concentration in heptane achi
eves 4%. The said parameters increase with the increasing monomer concentra
tion and temperature, while an increase in the initiator concentration caus
es these parameters to change in opposite directions.
