| 摘 要： | 在聚丙烯腈中加入少量丙烯腈-苯乙烯共聚物进行共混湿法纺丝,制得了内部具有大量微孔、吸水性能优良的共混纤维.本文从高聚物溶解度参数出发,应用Scott方程,对共混物相容性及相分离状态进行了预测,并运用相差显微镜对聚丙烯腈/丙烯腈-苯乙烯共聚物共混物的溶液及固体薄膜进行了研究,讨论了相容性与组成的关系.实验所得结果与分析预测完全一致.进一步研究了相容性及相结构与共混纤维微孔结构和亲水性能的关系,得到了一系列重要的结论.

| Abstract: | A series of porous hydrophilic acrylic fibers was made by adding a small amount of acrylonitrile-styrene copolymer (AS) into acrylic copolymer (PAC). By means of the equation proposed by Scott, we expected compatibility and phase separation in the blends from the concept of polymer solubility parameters and studied phase separation of PAC/AS films in solution as well as in solid state with phase contrast microscope. The relation between compatibility of PAC/AS blends and composition of AS copolymers was discussed, which is the same as the expectation from Scott equation. The effects of compatibility and phase structure on porous structure and hydrophilic properties of blend fibers were further investigated. Many important results were obtained. |
