| 摘 要： | 用粘度法测定了四氢呋喃/聚氯乙烯(THF/PVC)、THF/醋酸纤维素(CA)和THF/PVC/CA的特性粘数和高分子-高分子相互作用参数。以Δb′m判别法、Δη]m判别法和特性粘数—组成关系来判断PVC/CA的相容性,并以共混溶液折光指数随组成的变化来确定PVC/CA的相容性。实验结果均表明PVC/CA是一对相容性高聚物。

| Abstract: | The intrinsic viscosity and the viscometric interaction parameters have been experimentally measured for tetrahydrofuran(THF)/poly(vinyl chloride)(PVC) and THF/cellulose acetate (CA) as well as for THF/PVC/CA by viscometry,and also theoretically evaluated for the latter.The estimation of the PVC/CA miscibility has been done by means of three criteria: the sign of Δb~′_m?the sign of Δ_m and intrinsic viscosity-composition plot. The three criteria provide miscibility predictions.The study of variation of refractive index with blend composition also supports the obtained results. |
