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。

But undoubtedly, some factors such as the dual urban-rural economic structure slower the Chinese urbanization. How to accelerate the industrialization and urbanization in the situation of new socialist rural construction and overall development of the city and the countryside has been concerned by theorists and academia more and more. In particular, it is thoughtprovoking that how to construct the widely distributed small cities and optimize the township enterprise which makes a great contribution to economic development of China's countryside.

城乡分割对立的二元经济结构等因素导致的中国城镇化滞后于工业化是一个不争的事实，在建设社会主义新农村和统筹城乡的新形势下，如何更好地加快中国工业化和城镇化进程已日益受到理论界和学术界的关注，特别是如何对分布广泛的中国小城镇的建设，和对中国农村经济发展做出重大贡献的乡镇企业的成长进行优化和重整更是引人深思。
