CROSSLINKING AGENT FOR SOLID POLYELECTROLYTE, CROSSLINKED SOLID POLYELECTROLYTE PREAPRED USING SAME AND LITHIUM POLYMER SECONDARY CELL

Japanese Patent JP3328262

B2

PROBLEM TO BE SOLVED: To obtain a solid polyelectrolyte improved in mechanical properties and ionic conductivity by employing a crosslinking agent having a specific structure bearing plural unsaturated functional groups at its ends.
SOLUTION: The subject crosslinking agent bears three unsaturated functional groups on its ends and is represented by formula I (wherein, A is oxygen, COO, a 1-4C alkylene or a direct bond, formula II is cyclohexane, benzene, triazine, trioxane or isocyanurate; R1-R3 are each a 1-10C olefinic hydrocarbon, R4-R6 are each H or methyl; and (p), (q) and (r) are each 1-20), and preferably, tris(2- acryloyloxyethyl)isocyanurate or the like is employed. The crosslinking agent is employed preferably in an amount of 0.1-60 mass % based on the mass of a composition. The use of the crosslinking agent permits incorporation of at least 60 mass % of a polyethylene oxide-based oligomer into the composition unlike di- or tri-functional crosslinking agent composed solely of a soft segment such as a polyethylene glycol dimethacrylate or the like.
