Abstract

This chapter focuses on elucidating the mechanisms of interaction for a series of polymers adsorbed onto montmorillonite clay from aqueous solution. The polymers considered are nonionic, anionic and cationic polyacrylamide copolymers. The amount of polymer adsorbed, its conformation and the exact nature of the anchoring groups on the clay surface are considered. The nonionic polymers act as H-bond acceptors (amide and acid moieties) and donators (acid groups). The cationic copolymers exhibit strong, irreversible interactions with the clay. The anionic copolymers show only weak or no adsorption.
