摘　　要：在聚丙烯腈(PAN)基碳纤维前驱体的不同工业生产方法中,最常用的是在二甲基亚砜(DMSO)溶液中聚合纺丝,和在二甲基乙酰胺(DMAC)水相悬浮液中聚合纺丝。介绍了一种结合上述两种方法优点的新方法,即在工业上实现经水相悬浮聚合后再在DMSO中纺丝的两步法。该方法成功的关键,是由聚合物粉末和水性溶剂开始,有效地制备良好的纺丝溶液。Among the different processes industrially used for carbon fiber polyaury lonitrile(PAN)precursor production,the most popular are:solution polymelization and spinning in DMSO and water suspension polymerization followed by spinning in DMAC.A new approach is described which joins the advantages of both processes making it possible to industrially use a 2-step process with water suspension polymerization and spinning in DMSO.The key for success is the efficient preparation of a good spinning solution starting from polymer powder and aqueous solvent.
