| 摘 要： | 利用旋转粘度计和气压式毛细管流变仪等研究了助溶剂对二醋酸纤维素 -丙酮体系溶液性能的影响 ,并就助溶剂的作用机理进行了探讨 ,认为主要是由于助溶剂与二醋酸纤维素大分子链形成氢健的作用所致。理论估测与实验值能很好吻合

| Abstract: | The effect of the latent solvent on the properties of cellulose acetate (CA)-acetone solution was studied by rheometer.The viscosity (η),E η and spinnability of the solution decreased first and then increased with the amount of latent solvent increased,mainly because of the hydrogen-bond .Caculated results based on hydrogen-bond were matched with experimental data perfectly . |

| Keywords: | latent solvent cellulose acetate hydrogen-bond |
