A NEW ONE-POINT METHOD EQUATION DETERMINING INTRINSIC VISCOSITY
一个新的一点法测定特性粘数方程

The following new one-point method equation is obtained from the considerations of the relationship between the Huggins constant K' and the hydrodynamic and ther-modynamic interaction of polymer and solvent.Where x is polymer-solvent interaction parameter. Experimental data were tested, with satisfactory results.
