Abstract: The average association degree of PBOLi was measured by viscosity technique,Thus, the calculated results of the average association degree in the ion region of pseudo-gel obtained from thermodynamics and EHMO methods were verified by using this technique and its experimental data. Meanwhile, a new formula for measuring the average association degree of PBOLi in sub--concentrated solution by viscosity technique was also proposed.
