PURPOSE:To obtain an inexpensive thermally moldable hydrogen ion conductor for full cell by reacting a specific random copolymer with a strong base, reacting the reaction product with propanesultone, further acidifying the product, introducing sulfonic group in high density. CONSTITUTION:First, a random copolymer comprising units of formula I and formula II (R is H or methyl) in the ratio of the unit of formula I to the sum of the unit of formula I and the unit of formula II of 0.8-0.9 is reacted with a strong base and then with 1,3-propanesultone (derivative) of formula III (X and Y are H or 1-3C alkyl). Then, the reaction product is acidified, for example, by packing powder of the reaction product into a column, dripping an aqueous solution of a mineral acid from the top of the column to give the objective conductor composed of a thermally moldable copolymer having the ratio of the unit of formula I/the sum of units of formula I to formula III of 0.80.9 and the ratio of the unit of formula III to the sum of the units of formula II and formula III of 0.35-0.9. For example, dimsyl sodium of NaCH2-SOCH3 may be used as the strong base. |
