The present invention relates to an ion exchangeable polymer cross-linking agent having an electron withdrawing group, an ion conductive cross-linking polymer cross-linked by the cross-linking agent, and a use of the same. More specifically, without forming an ion exchangeable functional group as a primary or secondary amine cross-linking agent, cross-linking can be performed exclusively; and an electron withdrawing group is included, so a rapid cross-linking reaction is inhibited during membrane production, and thereby a change in the shape of a membrane can be prevented. In particular, dimension stability and mechanical stability caused by cross-linking are improved without affecting the functions, such as water uptake and conductivity, of a membrane. Also, a negative ion exchange functional group can be easily adjusted in the ion exchangeable polymer cross-linking agent. |
