A series of sulfonated polyimides （SPIs） containing pyridine groups were prepared by direct polycondensation from 1,4,5,8-naphthalenetetracarboxylic dianhydride （NTDA）, 4,4＇-diaminodiphenyl ether-2,2＇-disulfonic acid （ODADS） and 4-（4-methoxy）phenyl-2,6-bis（4-aminophenyl）pyridine （DAM）. The resulting...
