| 内容記述タイプ | Abstract | |||||
| 内容記述 | In an earlier paper, we proposed an exponential diffusion equation of wide application for the diffusion coefficient with concentration dependency : D=D。exp (AC-BC²)， and suggested that the concentration coefficient A and B should relate to the second virial coefficient derivative Γ₂ and the concentration coefficient of sedimentation coefficient kₛ. The relations between characteristics of diffusion curves and A or B can be gained by means of computer with satisfactory accuracy. In case of general polymer solutions which give positive skewness, A is positive or near zero and B is negative. Such as the regenerated cellulose from over-aged alkali cellulose gives nearly equal value of positive A and B, which results kurtosis smaller than 3. Plolymolecularity inclines both A and B to the negative side. In any way, it seems that each polymer has its individual region Γ₂/kₛ values and we can easily show it on the (A, B) coordinates. |
