Document Type and Number:
Japanese Patent JP4458213
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain an electrolyte excellent in ionic conductivity and film strength by a crosslinking reaction of a reactive polyalkylene oxide adding a reactive polyalkylene oxide and a lithium inorganic salt to a specified block graft copolymer. SOLUTION: To a block graft copolymer comprising block chains composed of a repeat unit of formula I and of repeat units of formula II and/or formula III, a reactive polyalkylene oxide and a lithium inorganic salt are added to perform a crosslinking reaction of a reactive polyalkylene oxide. Wherein each R2, R5 and R6 is H or CH3; each R1, R4 and R9 is R2 or C2H5; R3 is alkyl, aryl, acyl or the like; (n) is 1-100; a graft chain of a formula V in the formula I has number-average molecular weight of 45-4,400; M is CH=CH2, phenyl or the like; R7 is vinyl or the like; R8 is ethylene oxide or the like; (k) and (m) are each 0-25 but not 0 at the same time; (x) is -PhC(CH3)2PhO- or the like; and R10 to R12 are each CH3 or the like.
