Abstract: The present invention relates to a method for producing an acrylonitrile-based fiber, the method including: providing a polymer solution including an acrylonitrile-based copolymer containing a carboxylic acid group; mixing 100 parts by weight of the polymer solution with 1 to 6 parts by weight of a hydrophilization solution containing an organic solvent and ammonia water in a weight ratio of 95:5 to 60:40 to prepare a spinning stock solution; and spinning the spinning stock solution. The method controls the viscosity of the spinning stock solution to improve the stretchability and strength of the acrylonitrile-based fiber, and suppresses the occurrence of gelation.

Abstract: A polymerization initiator composition includes isomers of the polymerization initiator, thereby preventing instability and inertness of the polymerization initiator and physical property degradation of the SSBR, minimizing by-products and unreacted materials, and remarkably improving a conversion ratio. In addition, when the polymerization initiator composition according to the present invention is used, there is no need to add a polar additive separately upon polymer polymerization, since the polar additive is already added at the time of preparing the polymerization initiator. Further, the polymer initiator composition has high polarity so that the hydrophobic SSBR and the hydrophilic silica can be effectively dispersed.
