摘　　要：结合实际应用,对目前高吸水树脂溶胀理论研究现状进行了概述。从结构和热力学两个方面介绍了高吸水树脂的吸水理论,表明树脂的吸水跟其内在结构和吸水过程中的化学势有关。重点介绍了树脂的溶胀理论,阐述了Flory溶胀平衡理论的基本内涵,研究了温度、溶液的p H值、盐浓度等对溶胀过程的影响。最后介绍了溶胀过程中的动力学以及溶液在树脂中的扩散现象。The research situation of swelling theory of SAP was summarized with practical application.The absorbing mechanism of SAP was introduced by two aspects of structure and thermodynamics,which indicated that the water absorbing of resin was related to the intrinsic structure and chemical potential.The swelling mechanism of SAP was mainly introduced,which the basic connotation of Flory swelling equilibrium theory was expatiated.The dynamics of swelling process and the diffusion of solution in resin were introduced.
