To provide a crosslinking agent having a functional group capable of suppressing the degradation of resins and high polymerization rate and provide a crosslinked polymer having high stability, a gelatinous composition, a surface-modified substrate, an ion conductive composition produced by using the crosslinking agent and an electrochemical element produced by using the ion conductive composition.
The compound has carbodiimide group and/or urethodione group and a polymerizable unsaturated hydrocarbon group in the same molecule. The crosslinked polymer resistant to degradation and the surface-modified substrate can be produced by using the crosslinking agent containing the compound. A stable gelatinous composition, an ion conductive composition and an electrochemical element can be produced by using the crosslinked polymer.
