Abstract

The polymerization of acrylamide inside watcr-swollen micellas of Aerosol OT dispersed in toluene has been investigated. Incorporation of acrylamide enhances the interparticular attractive forces as shown by the intensity curves in small angle neutron scattering. It also induces sharp rises in conductivity which were attributed to a percolative process. The percolation threshold is lowered upon increasing the monomer content, reflecting the enhancement of the attractive interactions. In percolating systems, the structure affects the formation of polymer particles. Microscopy experiments show that particle nucleation occurs continuously throughout the polymerization.
