摘　　要：介绍了干法腈纶生产中,影响纺丝原液性能的主要指标是聚合物的特性粘度,考察催化剂、铁离子、pH值、聚合反应温度、烘干条件对特性粘度的影响,提出在生产中控制这些影响因素的对策。The intrinsic viscosity of polymer is the main characteristics that affect spinning solution properties in dry - spinning acrylic fiber process. The effects of catalyst quantities, iron ion amount, pH value, polymerization reaction temperature and drying conditions on intrinsic viscosity are studied in this paper. This paper also presents the methods of how to control these factors in the production.
