CATALYST FOR POLYMERIZING ACRYLONITRILE AND METHOD FOR PRODUCING POLYACRYLONITRILE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a polymerization catalyst capable of polymerizing acrylonitrile which is a kind of a polar vinyl monomer and having high polymerization activity and to provide a method for producing polyacrylonitrile. SOLUTION: The characteristic of this catalyst for polymerizing acrylonitrile is to comprise an iron complex containing cyclopentadienyl ligand and phosphine ligand and the characteristic of this method for producing polyacrylonitrile is to use the catalyst.
