摘要: Abstract This chapter describes the interactions of clay minerals with uncharged (nonionic) polymers, such as poly(vinyl alcohol), polyacrylamide, polyethylene glycol (polyethylene oxide) and polyvinyl pyrrolidone. Although ion–dipole, hydrogen bonding van der Waals are involved, adsorption polymers by smectites is an entropy-driven process. The clay–polymer interaction influenced nature exchangeable cations at surface. Both intercalation (by montmorillonite) increase polymer molecular weight but this effect may be offset a reduction in surface accessibility. Likewise, flocculating effectiveness increases weight.
