为制备强度较高、适合反冲洗的中空纤维膜，以水相悬浮聚合法制备得到ＵＨＭＷ－ＰＡＮ，研究了引发剂用量、单体浓度、聚合温度、聚合时间、搅拌速度和聚合釜大小对聚合物分子量的影响，在此基础上确定了制备所需ＵＨＭＷ－ＰＡＮ的合适工艺条件
In order to prepare UHMW-PAN with high strength and suitable for backwashing, UHMW-PAN was prepared by aqueous suspension polymerization. The effects of initiator dosage, monomer concentration, polymerization temperature, polymerization time, stirring speed and polymerization vessel size on polymerization On the basis of this, the suitable process conditions for preparing the desired UHMW-PAN were determined
