| 摘 要： | 本文从高分子溶液粘度和浓度依赖性中的斜率系数和高分子溶液流动时的流体力学及热力学因素之间关系着手,由9种高分子-溶剂体系的粘度数据,建立了一个新的一点法测定特性粘数方程。即: η]=η_(sp)/c/(1+1/2(1-x)η_(sp)) 此式不仅是一个一点法测定特性粘数的新的方程,而且也是一个由高分子溶液粘度数据估计高分子-溶剂相互作用参数X的方程。

| Abstract: | 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. |
