摘要：

The aqueous polymerization of methyl metacrylate in the presence of thiourea and hydrogen montmorillonite was initiated by radicals generated in situ. A part of the polymer was bound to the clay. Electrochemical analysis by cyclic voltammetry on this system and FeCl3/thiourea indicated that a slow one‐electron transfer process was responsible for the formation of the amidosulfenyl radical. The oxidant in the clay was lattice substituted Fe3+. Copyright © 1990 John Wiley & Sons, Inc.
