摘要：

Swelling equations are used to analyze the crosslinked structure of ionic hydrogels in contact with water. The equilibrium swelling ratio or equilibrium polymer volume fraction is shown to be a function of the polymer compatibility (as determined by the chi-1 factor), polymer structural parameters and the ionic nature of the hydrogels. Experimental swelling results for anionic hydrogels such as poly(2-hydroxy ethyl methacrylate-co-methacrylic acid) can be predicted by this model.
