Urethane acrylate anionomer was synthesized incorporating dimethylolpropionic acid (DMPA) on the molecular backbone as a water‐soluble oligomer. The solution behavior of the urethane acrylate anionomer was examined by viscosities as a function of the shear rate, temperature, and anionomer fraction. The logarithmic viscosities of the urethane acrylate anionomer solution followed well the Arrhenius equation and showed a linear relationship with the fraction and reciprocal temperature. So, it was possible to predict the viscosity of the urethane acrylate anionomer solution as functions of the fraction and reciprocal temperature, based on the rheological equation of state. The viscosities obtained from the equation of state successfully coincided with the results of the experiments. © 1998 John Wiley & Sons, Inc. J Appl Polym Sci 69: 1079–1088, 1998
