Polymerization of acrylamide with the redox couple Fe(III)/thiourea in the presence of the mineral clay montmorillonite has been investigated. Polyacrylamide is obtained in good yield having molecular weight (ca. 0.7–2.5 × 10 6 ) approximately one order of magnitude higher than without clay. Apparently, the locus of polymerization is the interlayer space of the clay.
