Abstract
A seeding procedure has been applied to inverse polyacrylamide microlatices in order to increase the final polymer content. The seed dispersions were prepared according to a microemulsion polymerization method. They consist of water-swollen polymer particles of small size (d < 500Å), stabilized by Aerosol OT and dispersed in toluene. Different amounts of acrylamide and AIBN initiator were added to the prepolymerized seed latices. Quasi-elastic light scattering experiments indicate that the added monomer polymerizes preferentially inside the polymer particles, leading to volume swelling ratios of 3 to 15. High dilutions induce structural changes in the final latex particles.
