Abstract
The locus of the initiation using the water-soluble radical initiator ammonium peroxodisulfate (APS) and/or the partially water-soluble radi cal initiator 2,2'-azoisobutyronitrile (AIBN) in the inverse microemul sion system toluene/water (mass ratio 10:1) was studied. The homopolym erization and/or copolymerization of the water-soluble monomer acrylam ide (AAM) with the oil-soluble methyl methacrylate (MMA) was investiga ted. It was found that the locus of initiation by APS in the given sys tem is the water micropool, and the locus of the initiation by AIBN is the interlayer between the water micropool and the toluene macrophase .
