|Abstract:||The viscosities of the maleic acid copolymers with styrene and vinyl acetate, which show electrochemically typical polydibasic characteristics, were studied mainly in aqueous medium and partly in acetone-water (1 : 1) mixture. The viscosity change due to the change in degree of neutralization at a given concentration reflected the polydibasic characteristics. The reduced viscosity as a function of concentration at a given degree of neutralization was studied at 25℃. Some data fitted Fuoss's equation for strong polyelectrolytes and some other did not fit. A general emipirical equation, ηsp/C=A/1-BC^π+D, was proposed for the viscometric data which did not fit Fuoss's equation. The values obtained for n in the above equation were constant at a given degree of neutralization and for a given polymer, and all were intermediate between one-half and one. The significance of n was discussed and the meanings of A and D in the above equation were also examined.|
