An object of the invention is to provide a process for industrially producing fluorinated dicyanobenzenes using tetrachlorodicyanobenzene as a raw material. According to the present invention, fluorinated dicyanobenzene can be produced in a high yield by allowing tetrachlorodicyanobenzenes to react with a fluorinating agent in the presence of a non-protonic polar solvent in an amount of 0.1 to 3 times by mass based on the tetrachlorodicyanobenzene. Further, the above production can be conducted more efficiently by reacting while disintegrating or removing bulk solid matters.

Poly(allylamine salts) of high polymerization degree is obtained in high yield by the polymerization of monoallylamine salt with a specified radical-polymerization initiator having in the molecule an azo group. Various poly(allylamine) derivatives are obtained by reacting said poly(allylamine salt) with acrylic compounds, or formic acid and formaldehyde.
