Poly(p‐phenylene sulfide sulfonic acid) was thermally crosslinked for use as a cation exchange polymer with high thermal stability. The decomposition temperature (Td) of the polymer increases with an increase in the crosslinking temperature. The crosslinking reaction at 300°C in air resulted in the formation of a strongly acidic cation exchange polymer with a T d 10% = 467°C and having an SO2 bond, whose crosslinked structure was investigated using IR spectroscopy.
