CROSS-LINKED POLYMER, ION CONDUCTIVE COMPOSITION, GEL STATE ION CONDUCTIVE COMPOSITION AND ELECTROCHEMICAL ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a cross-linked polymer having excellent durability and a means for utilizing the same. SOLUTION: This cross-linked polymer is obtained by copolymerizing a piperazine derivative having a water-and acid-capturing function and expressed by formula (A) with an aliphatic unsaturated bond-containing monomer. The ion conductive composition contains the cross-linked polymer and an electrolyte. The gel state ion conductive composition contains the ion conductive composition and a solvent. The electrochemical element contains the ion conductive composition. COPYRIGHT: (C)2004,JPO
