Abstract

L₁ and L₂ domains of the water/AOT/MMA ternary system were investigated at 22±1°C. Free radical polymerizations were conducted in L₂ domain. Only opaque polymer rods were obtained. Acrylamide, a water soluble monomer, plays a role of co-surfactant which greatly expands the L₂ domain. However, polymerizations only yielded opaque material. SEM showed images of phase separation.

MDOS (2-Methacryloyloxy)ethyl trimethylammonium bis(2-ethylhexyl) sulfosuccinate, was synthesized by ion exchange method. L₁ and L₂ domains of the water/MDOS/MMA ternary system were also investigated at 22±1°C. Free radical polymerizations were conducted in L₂ domain. Transparent polymer was produced. The “L₂” domain after polymerization was almost as large as L₂ domain. Polymerizations with acrylamide in the aqueous phase also produced transparent copolymer with up to 14% water. Polymer materials so produced were characterized by TGA, DSC, SEC, SEM.
