Abstract
PURPOSE: To obtain a diazonium base-containing polyether-sulfone which is useful as a photosensitive resin or a new type of raw material for the photosensitive resins, by the reaction of an amino group-containing polyether-sulfone having a specific repeating unit with nitrous acid (or a nitrite) in the presence of an acid.
CONSTITUTION: A diazonium base-containing polyether-sulfone consisting mainly of a repeating unit of the fomrula II (where X⊖ is a counter ion) is obtained by the reaction of an amino group-containing polyether polysulfone, having a repeating unit of the formula I [where Ar1 is a 6W10C (2+p) valent aromatic hydrocarbon group, Ar2 is a 6W10C (2+p) valent aromatic hydrocarbon group, Ar3 is a 6W15C divalent aromatic group, p and q are, respectively, 0W2, and p+q is 1W4], with nitrous acid, a nitrite salt, a nitrite ester etc., in the presence of an acid, followed by an aionic exchange as needed.
