A method for preparing a dicyanoalkane may omit a filtration for a catalyst after a cyanation reaction can by carrying out the cyanation reaction in a state in which precipitation of a metal catalyst is suppressed. A method for preparing a dicyanoalkane may involve cyanating one or more aliphatic dicarboxylic acids and/or salt(s) thereof with an ammonia source in the presence of a predetermined compound and a catalyst, wherein, in the cyanation, the amount of the predetermined compound is maintained at a predetermined amount or more with respect to the catalyst.
A method for preparing a functionalized polymer, the method comprising the steps of polymerizing monomer to form a reactive polymer, and reacting the reactive polymer with a polycyano compound.
