The stable or unstable state of the montmorillonite-water dispersion is mainly effected by the properties of montmorillonite, water, and stabilizers as well as their interactions, while the type, the structure, the properties and the concentration of the stabilizer play dominate roles. Based on the molecular designing clues, this research selected three sulfonated copolymers as the stabilizers, i.e. the sodium 2-acrylamido-2-methyl-1propane sulfonate /acrylamide /disodium itaconate terpolymer, the AMPS/AM/N-vinyl pyrrolidone terpolymer and the sodium styrenesulfonate /IA copolymer. The preparation and characterization of the sulfonated copolymers were discussed, the high-temperature stability of the montmorillonitewater dispersion was characterized with the rheology, the filtration, the particle size distribution, the electrostatic properties, and the adorption of the sulfonated copolymers onto montmorillonite particles. At the same time, a systematic mechanism of the hightemperature stabilization of the dispersion was presented.
