Time dependence of the conversion of acrylamide (AAm) initiated with potassium peroxodisulfate (KPS) was examined at various [AAm] and [KPS] in W/O microemulsions of 1,4-bis(2-ethylhexyl) sodium sulfobutanedioate in cyclohexane media at 45 °C. The rate of polymerization (<i>R</i><sub>p</sub>) calculated from the conversion-time profiles yielded the following equation: <i>R</i><sub>p</sub> ∝ [AAm]<sup>1.0</sup>[KPS]<sup>0.5</sup>. From these values of reaction orders for AAm and KPS, it was found that the polymerization of acrylamide in W/O microemulsions can be regarded as normal radical polymerization and biradical termination between polymer radicals.
