An investigative study of polymer adsorption onto montmorillonite clay
- Univ. of Southern Mississippi, Hattiesburg, MS (United States)
Few studies have been geared towards the study of the mechanisms governing stabilization and flocculation of polymers and clay particles. The overall goal of this research is to relate these mechanisms to properties above and below the critical overlap concentration, c*, of the polymer/clay species. Initially, phase behavior and sedimentation studies were conducted to screen for anionic, cationic and nonionic polymers capable of both flocculation and restabilization. As a result three polymers were selected for further testing: polyacrylamide, poly(acrylamide-co-acrylic acid) and poly(acrylamide-co-diallyldimethylammonium chloride). Polyacrylamide and poly(acrylamide-co-acrylic acid) have been synthesized and characterized by viscometry and {sup 13}C NMR. C* of the polymers was determined by viscometry via Huggins` plots and dynamic light scattering measurements have shown variations in the mean particle size as a function of polymer concentration.
