## Abstract The layered structure of clays with interlayer cations leads to unique chemical and mechanical properties, which have been capitalized on in the field of polymer/layered silicate nanocomposites. Hydrophilic silica surfaces can become organophilic with the inclusion of alkylammonium cati

## Abstract 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. 0.7β2.5 Γ 10^6^) approximately one order of magnitude higher than without
## 14), and Gan (15) concluded that the heat of immersion The enthalpy changes, DH, in suspensions of Li-, Na-, and depends on hydration of the particle surfaces as well as K-montmorillonite were determined as functions of the molal hydration of the exchangeable cations. Van der Marel (16) concent
