PROBLEM TO BE SOLVED: To provide a method for producing a polymer of acrylonitrile, and a copolymer and a multi-component copolymer comprising acrylonitrile and at least one other polymerizable comonomer. SOLUTION: (A) Acrylonitrile monomer, solvent, Forming a polymerizable mixture containing a sulfonyl halide, a halopropionitrile, a monoadduct derived from a sulfonyl halide and acrylonitrile, a substituted halopropionitrile, and a substituted sulfonyl halide. And a monoadduct derived from a monomer other than acrylonitrile, and an initiator selected from the group consisting of: and (C) polymerizing the acrylonitrile monomer to form a polymer consisting of acrylonitrile. How to include. |
