Abstract:
1. A process for producing a solid polymer electrolyte wherein at least components (a) and (b) below are reacted: (a) an acrylic copolymer comprising repeating units (Structural Unit I) represented by formula (I) below and repeating units (Structural Unit II) represented by formula (II) below in a molar ratio of from 1/5 to 1,000/1 and having a number average molecular weight of from 1,000 to 1,000,000 wherein R 1 is hydrogen or an alkyl group having 1 to 5 carbon atoms, R 2 is an alkyl group having 1 to 5 carbon atoms, R 3 and R 4 are each independently hydrogen or an alkyl group having 1 to 5 carbon atoms and are the same or different from each other, and m is an integer of from 0 to 100, and wherein R 5 is hydrogen or an alkyl group having 1 to 5 carbon atoms, R 6 and R 7 are each independently hydrogen or an alkyl group having 1 to 5 carbon atoms and are the same or different from each other, n is an integer of from 1 to 100, and X is an isocyanate group; and (b) a compound represented by formula (III) wherein R 8 is a divalent hydrocarbon group having 1 to 20 carbon atoms, and each Y is a hydroxyl group.
