Recently, scientists and engineers working on environmental and industrial problems have renewed their interests in water-soluble synthetic polymers primarily because of their broad range of applications. Polymer-surfactant interactions are not only of a diverse industrial interest but also stimulate academic investigations. Intercalation chemistry of phyllosilicates like vermiculite is gaining momentum rapidly to transform these abundant materials into selective heterogeneous catalysts. This book provides, detail aspect of kinetics and mechanism of the homo and copolymerization reactions of acrylamide in interlayer spaces of vermiculite, solution properties of polyacrylamide (PAM) in solvent mixtures (good and bad). The effects of the factors that control the expansion of polymer chains are discussed. The discussion would shed light on the understanding of interested readers of clay-catalysed polymerization (green way) of acrylamide, hydrodynamic properties of PAM under different conditions and it should also be useful to the researchers in the field of polymer chemistry and even the field of green chemistry (to exploit the tremendous catalytic potential of vermiculite).
