Abstract: The effect of pol acrylamide as an additive on preparation of inverse microemulsion toluene-AOT (AOT - sodium bis(2-ethylhexyl)sulfosuccinate)-water and on the properties of polymer particles resulting from the free-radical polymerization of acrylamide was studied. It was found that the amount of polyacrylamide which can be added without hindering the formation of tile inverse microemulsion depends on the toluene:AOT mole ratio (xr). Macroviscosity of the inverse microemulsion depends on the value of volume fraction of aqueous phase (water-acrylamide-polyacrylamide) φaw, in the inverse disperse system. Besides influencing the formation and stability of inverse microemulsion, the presence of polyacrylamide in the inverse micelles enormously increases the final polyacrylamide particle size. On the other hand, addition of polyacrylamide only marginally affects the molecular mass of polyacrylamide formed in polymer particles.
