Abstract
A crosslinked polymer with high ionic conductivity, an electrolyte using the crosslinked polymer and a process for producing the electrolyte, and a nonaqueous secondary battery using the electrolyte. Crosslinked polymers obtained by a crosslinking reaction between a compound having at least two substituents, in total, of at least one kind selected from the group consisting of &agr;,&bgr;-unsaturated sulfonyl, &agr;, &bgr;-unsaturated nitryl and &agr;,&bgr;-unsaturated carbonyl groups in its molecule and a compound having at least two nucleophilic groups in its molecule.
