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.

本文构筑了分子设计的思路，选取AMPS(2-丙烯酰胺基-2-甲基丙磺酸钠)/AM/IA三元共聚物、AMPS/AM/NVP三元共聚物和SSA/IA二元共聚物等三种磺化共聚物作为蒙脱土-水分散体系的高温稳定剂，进行了磺化共聚物稳定剂的制备与表征；从流变学、滤失性能、粒度分布、电性质以及磺化共聚物在蒙脱土上的吸附作用等方面，对蒙脱土-水分散体系的高温稳定性进行了研究，考察了蒙脱土-水分散体系的高温稳定性能，同时提出了高温稳定机理。

Just as when a man wanting to claritfy water has taken a katuka nut and put his hand inside the pot and rubbed it o-nce or twice the water does not come clear , he does not throw the katuka nut away; on the contrary he rubs it again and agin , and as he does so the fine mud subsides and the water becomes transparent and clear – so too, the bhikkhu should not give up , but he should again and again comprehend give attention to , discern and define materiality only."

注1：「…亦如想把水澄清的人，拿了迦答迦的子（一种胡桃的子，可以洗水缸清水）把手伸入水缸之内，经一二次的磨擦，水仍不能澄清，但他并不丢掉迦答迦的子，却数数磨擦，这样则污泥沈落而水自清。
