英文摘要：

Water-soluble polymers are widely used in petroleum development,water treatment,paper making,printing,medicine and so on,whose application at high temperature depends on their thermal stability. In this paper,the thermal performances of several typical water-soluble polymers are reviewed. Furthermore,the mechanisms of thermal degradation for different types of water-soluble polymers are revealed. In addition,the effect of molecular structure and external additives on thermal stability is discussed as well. Finally,the development prospects of watersoluble polymers utilized in high temperature environment are explored.
